My grandfather, Yu Xingye, said that your grandfather never bowed his head to anyone in his life. He was very tough and everyone was afraid of him.,But I think, I don't think what my grandpa Yu Xing said is reliable.,I sneakily asked my grandfather, "You get up early every day to cook, three meals a day, and then you go to work. You do this every day, even on legal holidays. Don't you ever get tired"。
