Chrysanthemum teaching is a network organization that opposes German-free people represented by Jing M.Guo. The purpose is to criticize and satirize the bad behaviors such as plagiarism and the vulgar trend in the entertainment circle through the internet in a spoof way.

Chrysanthemum teaching was born in Tianya Forum. Godmother is Jing M.Guo. Because he is feminine, he is called chrysanthemum.

Godmother is also called "yeast"

Now there is a new saying on the Internet that GJM (Jing M.Guo) = GJM (dry yeast).
