The topics given are not their strengths, they have not been systematically trained, they are too poor, and there is too little financial support for academics. Because of lack, academic rubbish has entered such an infinite cycle, and many academics have no practical significance, and they are also linked to fame and fortune, which is simply shameless. Any valuable article is either inspired by generate or thought by generate, so "the article is natural, and it is rare". But now the papers are forced out, there is no inspiration and thought explosion, so there is no way to avoid garbage.
