Wei Zi website recommended.

The teaching handouts were all written by Mr. Weiyang himself, and the questions published in the forum were mainly answered by Mr. Yang. Mr. Zi Weiyang thought that Mr. Yang had enough ability to answer these questions, so he was given the opportunity to answer them, but the answers to all the questions were reviewed by Mr. Zi Weiyang himself. Interested in seeing ziweiyang.com.
