What do you mean by non-mainstream? How many kinds are there? Come on, everybody, 3Q.
Non-mainstream, I don't want to define it by mainstream. Because it is easy to fall into the cycle paradox of chicken or egg first. Do it backwards! It is rebellious, flamboyant, wild and weird ... a few people show their fashion. This is non-mainstream! You are born after 90, right? Ha ha! !
