According to Zhang Yu's own statement, eight sets of volumes are for you to check for leaks and fill vacancies, not for the topic, but for your weak links, which is definitely difficult. Zhang Yu's lecture is easy to explain, but when it comes to mathematics level, it is still not the same as Tang's professional mathematics department. However, teaching postgraduate mathematics is enough. In short, it is more interesting to listen to Zhang Yu in class, and Li Lin is more practical in taking papers.
