It should be said that girls didn't know how to dress up before they went to college at the 18th National Congress. They are all absorbed in their study.

Of course, after some people move from a closed environment to a larger and more complex environment, their temperament will change to a certain extent, which has both subjective and objective reasons. But this is not absolute.
