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.,One late night, I was hungry and got out of bed to find something to eat. As I passed by my grandmother's room, the door was slightly ajar. Out of curiosity, I peeked inside, and what I saw almost made me jump.,“Your grandfather was warming your grandmother's feet. Your grandmother wasn't feeling well and always had cold hands and feet. Your grandfather felt sorry for her. Just pretend you didn't see it, don't ever tell your grandfather about this.”。
