I feel the same way about it. Liu Yanxia, the teacher of Global Economic Basis, has detailed lecture notes, outstanding viewpoints and rich cases. He made it clear which is the key and which is not, and business knowledge came with his mouth open. It can be said that with a simple economic foundation, you can pass the exam without reading books as long as you memorize the handouts.

In contrast, Liu Shu E, a lecturer in world intermediate finance, runs counter to it. Her class notes are only the outline of the textbook, and the explanation is the phonetic version of her class notes. And she often gets stuck and repeats what she said regardless of the key points. For example, she will say "1+ 1=2", and she will say "Let's look at an example, ah, look at an example. What is this question about? Even after-school exercises are rarely analyzed. Is it a different teaching style or irresponsible?
