Lu Yu seems to really like eating sweets. He can take out one from anywhere and there is no end to it.
Bai Yanzhi: Where did you get so much sugar?
Lu Yu: I don't know either. (Take out a candy) Do you want to eat it?
Bai Yanzhi: ... Children should not eat too much sugar.
Later, Bai Yanzhi would often stare at Lu Yu's tombstone in a daze, and before leaving, she would take out a candy, which was her favorite lemon flavor.
"Do you want to eat it?" "Children still need to eat more sweets."
Intention: Don't try easily without being sure that you can do two things well at the same time.
