There was an old lady in the village who had the right idea, and after the old man was gone, a son and three girls asked the old lady to go to the homes of several children and daughters.
But the old lady said, I will live in my own house without going, and if you really have filial piety, you will come and serve me. The old lady is a civil servant and has a pension.
Since then, several of her children have rotated (for a week) to serve the old lady. Old lady, now 98 years old, the body is still very hard!
