My neighbor, Brother Liu, is famous for his filial piety in the neighborhood. Whatever his parents want to eat, he will immediately buy it and take it home without saying a word. Every time I go back to my hometown, I bring a lot of things in big and small bags, including food, clothing and everything.

Others come home every ten days and a half or even once a month, but he comes home every week or so, sometimes twice a week. In other families, parents prepare a table of delicious food for their children to come home to eat. Brother Liu always cooks it at home and then enjoys the food with his parents.

All in all, Brother Liu really had nothing to say to his parents. The elders in the village say that Brother Liu's parents are lucky.

But the two old people also have troubles, that is, Brother Liu also likes to buy medicine for the elderly. Buy it when you’re not feeling well, and take various supplements when you’re feeling well. The old man thought that his usual headaches and colds could be cured without taking medicine, but Brother Liu didn't think so. When you are sick, you have to take medicine. Brother Liu does a good job and buys better medicine. But who likes to take medicine?
