Dr. Li Changyi donated some of his case tools and honor certificates in his decades of criminal investigation work, such as badges, hats, photos, and works, etc. to his hometown Rugao. Here, he held the Li Changyi Criminal Investigation Technology Museum. I think it is particularly good. It is as an expression of overseas Chinese patriotic love for the hometown, but also for the children of Rugao to provide a place to learn, Dr. Li's deeds are particularly inspirational, his family, his education, his growth, especially his famous saying: turn the impossible into the possible, It must be impressive for a child, it is to cultivate and encourage their courage to challenge the temperament. It is especially helpful for children's character development. If the museum can do more activities, such as holding a small Sherlock summer camp, etc., it will definitely attract many parents.
