There is a Qingshi Alley at the end of Tongcheng West Street. If you post a letter in the mailbox at the alley, if there is a paper swallow the next day, it means they have accepted your request. There are three irregularities in looking for people, seeking justice, and handling difficult things: don't kill innocent people, don't harm good people, and don't go against your true intentions.
Seven people live here - Shen Huaizhou, Lin Yan, Su Ci, Liu Mian, Jiang Yu, Gu Xingzhou and Xu Zhile. Not related by blood, but we are a family.
Later, one by one left. Every time a person walks away, another lantern hangs on the locust tree at the entrance of the alley. The trees are full and the alleys are empty.
Only the youngest one is left, waiting at the alley every day.
The mailbox was rusty, but he still wiped it every day.
Intention: What people fear most in this life is not losing, but finding everything for others.
