Sun Zu was born in Nanjing, 1905. His great-grandfather, Sun Zhaoying, came to Farah from Huize Bridge to do business and started the family history of six generations living under one roof. Sun family has been farming for generations, hardworking, simple and kind. Great-grandparents stole a few words and bought a lot of thread-bound books when recording other people's wedding ceremony books. These old books were copied and burned when they were broken. He is very diligent. When plowing the land, he makes several pairs of cows every day, changing cows halfway, and people don't rest. Hold the plough handle in one hand and eat buckwheat Baba in the other. Grandfather Sun Chaoan was educated in the "normal class" and later took part in the revolution. After liberation, he has been a clerk. Because of his integrity and justice, no one was killed or starved to death in the ultra-left era. Father Sun Zhengguo went to work in the commune post office, but his grandfather Sun Chaoan forced him to retreat. He never left the land and poverty in his life.

The young Sun Shixiang was sickly since childhood, because his mother didn't have enough milk. Before I was three years old, I suffered from mumps, sore throat and other diseases. Crying all the year round, resulting in red eyes, wrinkled face, abnormal slow and timid response. Often scared by passers-by, hiding in a pile of hair.
