“Wow,” Tongtong said. “You are a robot?”
The face smiled. “Hello there! Ah Fu is my name.”
“Can I touch you?”
“Sure!”
Tongtong put her hand against the smooth face, and then she felt the robot’s arms and hands. Ah Fu’s body was covered by a layer of soft silicone, which felt as warm as real skin.
Dad told Tongtong that Ah Fu was made by Guokr Technologies, Inc., and it was a prototype. Its biggest advantage was that it was as smart as a person: it knew how to peel an apple, how to pour a cup of tea, even how to cook, wash the dishes, embroider, write, play the piano . . . Anyway, having Ah Fu around meant that Grandpa would be given good care.
Grandpa sat there, still stone-faced, still saying nothing.
After lunch, Grandpa sat on the balcony to read the newspaper. He dozed off after a while. Ah Fu came over noiselessly, picked up Grandpa with his strong arms, carried him into the bedroom, set him down gently in bed, covered him with a blanket, pulled the curtains shut, and came out and shut the door, still not making any noise.
Tongtong followed Ah Fu and watched everything.
Ah Fu gave Tongtong’s head a light pat. “Why don’t you take a nap, too?”
Tongtong tilted her head and asked, “Are you really a robot?”
Ah Fu smiled. “Oh, you don’t think so?”
Tongtong gazed at Ah Fu carefully. Then she said, very seriously, “I’m sure you are not.”
“Why?”
“A robot wouldn’t smile like that.”
“You’ve never seen a smiling robot?”
“When a robot smiles, it looks scary. But your smile isn’t scary. So you’re definitely not a robot.”
Ah Fu laughed. “Do you want to see what I really look like?”
Tongtong nodded. But her heart was pounding.
Ah Fu moved over by the video wall. From on top of his head, a beam of light shot out and projected a picture onto the wall. In the picture, Tongtong saw a man sitting in a messy room.
The man in the picture waved at Tongtong. Simultaneously, Ah Fu also waved in the exact same way. Tongtong examined the man in the picture: he wore a thin, grey, long-sleeved bodysuit, and a pair of grey gloves. The gloves were covered by many tiny lights. He also wore a set of huge goggles. The face behind the goggles was pale and thin, and looked just like Ah Fu’s face.
Tongtong was stunned. “Oh, so you’re the real Ah Fu!”
The man in the picture awkwardly scratched his head, and said, a little embarrassed, “Ah Fu is just the name we gave the robot. My real name is Wang. Why don’t you call me Uncle Wang, since I’m a bit older?”
Uncle Wang told Tongtong that he was a fourth-year university student doing an internship at Guokr Technologies’ R&D department. His group developed Ah Fu.
He explained that the aging population brought about serious social problems: many elders could not live independently, but their children had no time to devote to their care. Nursing homes made them feel lonely and cut off from society, and there was a lot of demand for trained, professional caretakers.
But if a home had an Ah Fu, things were a lot better. When not in use, Ah Fu could just sit there, out of the way. When it was needed, a request could be given, and an operator would come online to help the elder. This saved the time and cost of having caretakers commute to homes, and increased the efficiency and quality of care.
The Ah Fu they were looking at was a first-generation prototype. There were only three thousand of them in the whole country, being tested by three thousand families.
Uncle Wang told Tongtong that his own grandmother had also been ill and had to go to the hospital for an extended stay, so he had some experience with elder care. That was why he volunteered to come to her home to take care of Grandpa. As luck would have it, he was from the same region of the country as Grandpa, and could understand his topolect. A regular robot probably wouldn’t be able to.
Uncle Wang laced his explanation with many technical words, and Tongtong wasn’t sure she understood everything. But she thought the idea of Ah Fu splendid, almost like a science fiction story.
“So, does Grandpa know who you really are?”
“Your mom and dad know, but Grandpa doesn’t know yet. Let’s not tell him, for now. We’ll let him know in a few days, after he’s more used to Ah Fu.”
Tongtong solemnly promised, “Don’t worry, eh!”
She and Uncle Wang laughed together.
Grandpa really couldn’t just stay home and be idle. He insisted that Ah Fu take him out walking. But after just one walk, he complained that it was too hot outside, and refused to go anymore.
Ah Fu told Tongtong in secret that it was because Grandpa felt self-conscious, having someone push him around in a wheelchair. He thought everyone in the street stared at him.
But Tongtong thought, Maybe they were all staring at Ah Fu.
Since Grandpa couldn’t go out, being cooped up at home made his mood worse. His expression grew more depressed, and from time to time he burst out in temper tantrums. There were a few times when he screamed and yelled at Mom and Dad, but neither said anything. They just stood there and quietly bore his shouting.
But one time, Tongtong went to the kitchen and caught Mom hiding behind the door, crying.
Grandpa was now nothing like the Grandpa she remembered. It would have been so much better if he hadn’t slipped and got hurt. Tongtong hated staying at home. The tension made her feel like she was suffocating. Every morning, she ran out the door, and would stay out until it was time for dinner.
Dad came up with a solution. He brought back another gadget made by Guokr Technologies: a pair of glasses. He handed the glasses to Tongtong and told her to put them on and walk around the house. Whatever she saw and heard was shown on the video wall.
“Tongtong, would you like to act as Grandpa’s eyes?”
Tongtong agreed. She was curious about anything new.
Summer was Tongtong’s favorite season. She could wear a skirt, eat watermelon and popsicles, go swimming, find cicada shells in the grass, splash through rain puddles in sandals, chase rainbows after a thunderstorm, get a cold shower after running around and working up a sweat, drink iced sour plum soup, catch tadpoles in ponds, pick grapes and figs, sit out in the backyard in the evenings and gaze at stars, hunt for crickets after dark with a flashlight . . . In a word: everything was wonderful in summer.
Tongtong put on her new glasses and went to play outside. The glasses were heavy and kept on slipping off her nose. She was afraid of dropping it.
Since the beginning of summer vacation, she and more than a dozen friends, both boys and girls, had been playing together every day. At their age, play had infinite variety. Having exhausted old games, they would invent new ones. If they were tired or too hot, they would go by the river and jump in like a plate of dumplings going into the pot. The sun blazed overhead, but the water in the river was refreshing and cool. This was heaven!
Someone suggested that they climb trees. There was a lofty pagoda tree by the river shore, whose trunk was so tall and thick that it resembled a dragon rising into the blue sky.
But Tongtong heard Grandpa’s urgent voice by her ear: “Don’t climb that tree! Too dangerous!”
Huh, so the glasses also act as a phone. Joyfully, she shouted back, “Grandpa, don’t worry, eh!” Tongtong excelled at climbing trees. Even her father said that in a previous life she must have been a monkey.
But Grandpa would not let her alone. He kept on buzzing in her ear, and she couldn’t understand a thing he was saying. It was getting on her nerves, so she took off the glasses and dropped them in the grass at the foot of the tree. She took off her sandals and began to climb, rising into the sky like a cloud.
This tree was easy. The dense branches reached out to her like hands, pulling her up. She went higher and higher and soon left her companions behind. She was about to reach the very top. The breeze whistled through the leaves, and
sunlight dappled through the canopy. The world was so quiet.
She paused to take a breath, but then she heard her father’s voice coming from a distance: “Tongtong, get . . . down . . . here . . . ”
She poked her head out to look down. A little ant-like figure appeared far below. It really was Dad.
On the way back home, Dad really let her have it.
“How could you have been so foolish?! You climbed all the way up there by yourself. Don’t you understand the risk?”
She knew that Grandpa told on her. Who else knew what she was doing?
She was livid. He can’t climb trees any more, and now he won’t let others climb trees, either? So lame! And it was so embarrassing to have Dad show up and yell like that.
The next morning, she left home super early again. But this time, she didn’t wear the glasses.
“Grandpa was just worried about you,” said Ah Fu. “If you fell and broke your leg, wouldn’t you have to sit in a wheelchair, just like him?”
Tongtong pouted and refused to speak.
Ah Fu told her that through the glasses left at the foot of the tree, Grandpa could see that Tongtong was really high up. He was so worried that he screamed himself hoarse, and almost tumbled from his wheelchair.
But Tongtong remained angry with Grandpa. What was there to worry about? She had climbed plenty of trees taller than that one, and she had never once been hurt.
Since the glasses weren’t being put to use, Dad packed them up and sent them back to Guokr. Grandpa was once again stuck at home with nothing to do. He somehow found an old Chinese Chess set and demanded Ah Fu play with him.
Tongtong didn’t know how to play, so she pulled up a stool and sat next to the board just to check it out. She enjoyed watching Ah Fu pick up the old wooden pieces, their colors faded from age, with its slender, pale white fingers; she enjoyed watching it tap its fingers lightly on the table as it considered its moves. The robot’s hand was so pretty, almost like it was carved out of ivory.
But after a few games, even she could tell that Ah Fu posed no challenge to Grandpa at all. A few moves later, Grandpa once again captured one of Ah Fu’s pieces with a loud snap on the board.
“Oh, you suck at this,” Grandpa muttered.
To be helpful, Tongtong also said, “You suck!”
“A real robot would have played better,” Grandpa added. He had already found out the truth about Ah Fu and its operator.
Grandpa kept on winning, and after a few games, his mood improved. Not only did his face glow, but he was also moving his head about and humming folk tunes. Tongtong also felt happy, and her earlier anger at Grandpa dissipated.
Only Ah Fu wasn’t so happy. “I think I need to find you a more challenging opponent,” he said.
When Tongtong returned home, she almost jumped out of her skin. Grandpa had turned into a monster!
He was now dressed in a thin, grey, long-sleeved bodysuit, and a pair of grey gloves. Many tiny lights shone all over the gloves. He wore a set of huge goggles over his face, and he waved his hands about and gestured in the air.
On the video wall in front of him appeared another man, but not Uncle Wang. This man was as old as Grandpa, with a full head of silver-white hair. He wasn’t wearing any goggles. In front of him was a Chinese Chess board.
“Tongtong, come say hi,” said Grandpa. “This is Grandpa Zhao.”
Grandpa Zhao was Grandpa’s friend from back when they were in the army together. He had just had a heart stent put in. Like Grandpa, he was bored, and his family also got their own Ah Fu. He was also a Chinese Chess enthusiast, and complained about the skill level of his Ah Fu all day.
Uncle Wang had the inspiration of mailing telepresence equipment to Grandpa and then teaching him how to use it. And within a few days, Grandpa was proficient enough to be able to remotely control Grandpa Zhao’s Ah Fu to play chess with him.
Not only could they play chess, but the two old men also got to chat with each other in their own native topolect. Grandpa became so joyous and excited that he seemed to Tongtong like a little kid.
“Watch this,” said Grandpa.
He waved his hands in the air gently, and through the video wall, Grandpa Zhao’s Ah Fu picked up the wooden chessboard, steady as you please, dexterously spun it around in the air, and set it back down without disturbing a piece.
Tongtong watched Grandpa’s hands without blinking. Are these the same unsteady, jerky hands that always made it hard for Grandpa to do anything? It was even more amazing than magic.
“Can I try?” she asked.
Grandpa took off the gloves and helped Tongtong put them on. The gloves were stretchy, and weren’t too loose on Tongtong’s small hands. Tongtong tried to wiggle her fingers, and the Ah Fu in the video wall wiggled its fingers, too. The gloves provided internal resistance that steadied and smoothed out Tongtong’s movements, and thus also the movements of Ah Fu.
Grandpa said, “Come, try shaking hands with Grandpa Zhao.”
In the video, a smiling Grandpa Zhao extended his hand. Tongtong carefully reached out and shook hands. She could feel the subtle, immediate pressure changes within the glove, as if she were really shaking a person’s hand—it even felt warm! This is fantastic!
Using the gloves, she directed Ah Fu to touch the chessboard, the pieces, and the steaming cup of tea next to them. Her fingertips felt the sudden heat from the cup. Startled, her fingers let go, and the cup fell to the ground and broke. The chessboard was flipped over, and chess pieces rolled all over the place.
“Aiya! Careful, Tongtong!”
“No worries! No worries!” Grandpa Zhao tried to get up to retrieve the broom and dustpan, but Grandpa told him to remain seated. “Careful about your hands!” Grandpa said. “I’ll take care of it.” He put on the gloves and directed Grandpa Zhao’s Ah Fu to pick up the chess pieces one by one, and then swept the floor clean.
Grandpa wasn’t mad at Tongtong, and didn’t threaten to tell Dad about the accident she caused.
“She’s just a kid, a bit impatient,” he said to Grandpa Zhao. The two old men laughed.
Tongtong felt both relieved and a bit misunderstood.
Once again, Mom and Dad were arguing with Grandpa.
The argument went a bit differently from before. Grandpa was once again repeating over and over, “Don’t worry, eh!” But Mom’s tone grew more and more severe.
The actual point of the argument grew more confusing to Tongtong the more she listened. All she could make out was that it had something to do with Grandpa Zhao’s heart stent.
In the end, Mom said, “What do you mean? ‘Don’t worry’? What if another accident happens? Would you please stop causing more trouble?”
Grandpa got so mad that he shut himself in his room and refused to come out, even for dinner.
Mom and Dad called Uncle Wang on the videophone. Finally, Tongtong figured out what happened.
Grandpa Zhao was playing chess with Grandpa, but the game got him so excited that his heart gave out—apparently, the stent wasn’t put in perfectly. There had been no one else home at the time. Grandpa was the one who operated Ah Fu to give CPR to Grandpa Zhao, and also called an ambulance.
The emergency response team arrived in time and saved Grandpa Zhao’s life.
What no one could have predicted was that Grandpa suggested that he go to the hospital to care for Grandpa Zhao—no, he didn’t mean he’d go personally, but that they send Ah Fu over, and he’d operate Ah Fu from home.
But Grandpa himself needed a caretaker too. Who was supposed to care for the caretaker?
Further, Grandpa came up with the idea that when Grandpa Zhao recovered, he’d teach Grandpa Zhao how to operate the telepresence equipment. The two old men would be able to care for each other, and they would have no need of other caretakers.
Grandpa Zhao thought this was a great idea. But both families thought the plan absurd. Even Uncle Wang had to think about it for a while and then said, “Um . . . I have
to report this situation to my supervisors.”
Tongtong thought hard about this. Playing chess through Ah Fu was simple to understand. But caring for each other through Ah Fu? The more she thought about it, the more complicated it seemed. She was sympathetic to Uncle Wang’s confusion.
Sigh, Grandpa is just like a little kid. He wouldn’t listen to Mom and Dad at all.
Grandpa now stayed in his room all the time. At first, Tongtong thought he was still mad at her parents. But then, she found that the situation had changed completely.
Grandpa got really busy. Once again, he started seeing patients. No, he didn’t go to the clinic; instead, using his telepresence kit, he was operating Ah Fus throughout the country and showing up in other elders’ homes. He would listen to their complaints, feel their pulse, examine them, and write out prescriptions. He also wanted to give acupuncture treatments through Ah Fus, and to practice this skill, he operated his own Ah Fu to stick needles in himself!
Uncle Wang told Tongtong that Grandpa’s innovation could transform the entire medical system. In the future, maybe patients no longer needed to go to the hospital and waste hours in waiting rooms. Doctors could just come to your home through an Ah Fu installed in each neighborhood.
Uncle Wang said that Guokr’s R&D department had formed a dedicated task force to develop a specialized, improved model of Ah Fu for such medical telepresence applications, and they invited Grandpa onboard as a consultant. So Grandpa got even busier.
Since Grandpa’s legs were not yet fully recovered, Uncle Wang was still caring for him. But they were working on developing a web-based system that would allow anyone with some idle time and interest in helping others to register to volunteer. Then the volunteers would be able to sign on to Ah Fus in homes across the country to take care of elders, children, patients, pets, and to help in other ways.
If the plan succeeded, it would be a step to bring about the kind of golden age envisioned by Confucius millennia ago: “And then men would care for all elders as if they were their own parents, love all children as if they were their own children. The aged would grow old and die in security; the youthful would have opportunities to contribute and prosper; and children would grow up under the guidance and protection of all. Widows, orphans, the disabled, the diseased—everyone would be cared for and loved.”
