How can I evaluate such a grandfather? Can you give me some advice?

Actually, it's very simple! ~ People like your father-in-law are very nice! ~~

Really warm heart! ~ although sometimes dedication does not take into account the feelings of family members.

But his starting point is good! ~

My father is a bit like him, and my mother is also very angry.

But what we children can do is to be filial to his old man. As long as he is happy, happiness is the happiness of a family.

He is old now! ~ the whole family should let the children take over! ~

From what you said, it seems that you don't quite agree with what your father-in-law did. ...

There must be understanding and tolerance under the same roof! ~

Say he doesn't want it, it will make trouble. ...

From his point of view, there are actually some things worth doing! ~

Say it again,

The old man worked hard all his life. As long as it's not too much, let him have fun. ...

I wish your family happiness! ~~~
