The little devil who lives in Tongjie must be Lou Yan
A good big brother to his peers, a negative example in the eyes of his parents, and a good grandchild to his grandma.
Ask around and ask who doesn't know who Lou Yanyan is?
Not to mention Lou Yanyan, no one really knows it, but when the name Lou Yan comes out, all the dogs passing by will salivate before leaving.
Purpose: Everything is for learning
