I see that Baobei isn't neutered, and a type of tumor called a perianal adenoma are common in intact males. There is a malignant version of this tumor called a perianal adenocarcinoma, and while it is is less common that the perianal adenoma, it carries a fair to guarded prognosis. I would have him seen by a vet to diagnose if this growth is benign or malignant, and the vet can discuss treatment options with you.
