On the day he left, he just said, Su Yang, I don't know when I will come back. Dad didn't say. I can't study with you in high school. I went to high school in Beijing and didn't take the high school entrance examination. You take good care of yourself, study hard, and start well. In the future, if you take the university entrance examination in Beijing, can we go together again? When we met again, he said, I want this painting. Finally, I went through those years when you didn't accompany me to fulfill my wish.
