In terms of teaching materials, foreign Man Kun is relatively easy to understand, while domestic Gao Hongye edition is relatively obscure.

Personally, I think it's ok after learning. It is important to understand the concept. If you don't understand the basic knowledge, it is difficult to learn later, and it is also important to understand the model. As for videos, you can go to Netease open class to see some videos of professors at home and abroad. Economics is a highly theoretical discipline with high requirements for mathematics and wide practical application. I hope it helps you.
