When Nanche was three years old, Shu Xin was born prematurely; when Nanche was five years old, he always went to the hospital because of his frailty. Shuqin also went to the hospital with him. The reason was that Shuqin suffered from congenital heart disease (a small hole in the heart) due to premature birth. When Nan Che was 8 years old, he watched Shu Qin being pushed into the operating room with tears in his eyes, and secretly made up his mind to protect her in this life; when Nan Che was 13 years old, he looked into Shu Qin's dark eyes and said, "If you want to dance, I will learn it. If you can't do strenuous exercise, I will run. If you play basketball, just watch me. I will help you with everything you want to do but can't do." . . . . . . . .
