The old man is 2023 102 years old, with four sons and one daughter, all in their seventies and eighties. Five generations of the whole family live under one roof, with more than 100 people.
The old man is in good health now. He hasn't taken medicine for years. He can clearly see the time on his watch. He often rides a bike in the village, likes playing cards and watching movies, and meets his great-grandson once or twice a week.
