He has taught hundreds of students from Canada, Germany, Hong Kong, Poland, Singapore, Taiwan, and the United States.

His co-author Philip Straus wrote: "Mr. Yang has a comprehensive understanding of the meaning of josekis. More importantly, he has developed a method to transfer that understanding to amateur players who grope about in a fog of confusion when trying to puzzle out even the simplest joseki."

He has created hundreds of life-and-death problems. He also has translated multiple Go books from Japanese into Chinese.

He enjoys "sports and cooking Chinese food."
