How about taking ps and Yifan education classes?

This online teaching mode is quite suitable for me and can avoid all kinds of troubles brought by offline teaching. There was a time when I attended an offline training class, and I spent a lot of time on the road, so it was difficult to stick to it. Now there are online class replays, which can better arrange the time reasonably and finish the homework online. You can ask the teacher directly if you have any questions.
