Yu Guanghui was born in a poor mountain village. His father, Zhang Shan, ran away from home when he was young and has not been heard from since. A year after my father left, my mother couldn't bear the burden of life and left him cruelly. Yu Guanghui, who was only a few years old, could only depend on his elderly grandmother. Later, his grandmother remarried to a family with the same surname, and he changed his surname accordingly. In those difficult days, he experienced all the sufferings of the world as a child, often had little to eat, and was bullied by his peers, but he always harbored a yearning for a better life in his heart.
