Yu Meiren didn't say she was a doctor because Yu Meiren turned to fashion bloggers. Yu Meiren is the host of the TV program "Little Forest for Two". Yu Meiren asked Zhuang Yu and Zhuang Yu not to go on a date and told others that she didn't like stupid girls, so she didn't go on a date with Yu Meiren. After being heard by Yu Meiren, she became a doctor of ornithology. But later, instead of working professionally, Yu Meiren turned to a fashion blogger. She felt that Zhuang Yu didn't like herself anyway, so there was no need to tell him that she was a doctor. Therefore, Yu Meiren didn't say that she was a doctor, because Yu Meiren turned to fashion bloggers.
