Did Xu and Crystal break up?

No, although the photos of Crystal and her boyfriend were taken by all-stars, neither side has responded so far, and the identity of the man has always been a mystery. The only information that can be dug up is that this person's name is Xu, and he is a prominent person. At present, he is the owner of a well-known hotel in China, and the rest are ignorant. His Weibo doesn't even have any blog posts. The only one is Weibo, who is doing public welfare with Crystal.
