Summer sunset.
Xizhao's father committed suicide when he was eight years old, and his mother disappeared.
Then he was taken to Xicheng to live with his grandparents.
Xicheng is a place where every house has a yard, full of flowers and plants. Especially in midsummer, the bluebirds are in full bloom.
It was in Xicheng that I met Xishu.
Xizhao is 8 years old and Xishu is 22 years old. They are 14 years apart.
