What is the main content and brief introduction of Liang's father?

In my mind, he is the head of the family, an absolute authority, and a benefactor who sells his physical strength to provide me with food and clothing.

My father is a strong Shandong man, who never complains about life and never sighs. Father made us eat him with a straight face. Father's life principle-everything is Dont Ask For Help. Neighbors said that our house: "There is a door on the roof, and the house should be drilled." I often pray that my father will complain about something and sigh. Because I heard an old lady who can tell a fortune nearby say, "Everyone has a breath in his chest." According to my naive idea, if my father sighs, he will lose his temper less. This is probably the father's "fate" decision? What a pity! I feel sorry for my father and family. But when my father lost his temper, I understood. Even sympathize with him. A person can't do anything about his life. Others can't help this man's life. Besides, we eat dad every day. Don't we allow people who are "eaten" every day to lose their temper with us?
