Ding was accused of catfish for two main reasons. First of all, there are two unknown black lines beside its mouth, and sometimes its mouth will have two nests when it is tilted up, which looks like catfish, so it is called "catfish". In addition, some people think that this is because he has the characteristics of catfish, which has been recognized by some fans. Although this description may be ridiculous, it is mainly because fans have an interesting and relaxed discussion about his appearance and image. Please note that these are just fan descriptions, not demeaning or insulting Ding himself. Ding's image and charm as an artist should not be defined only by his appearance.
