I didn't have a diploma after studying in Gu Wei's Fang Shi.

Does the subject want to ask, "Why didn't you have a diploma after reading in Gu Weifang?" Because the antique room is not a formal discipline or major. According to relevant public information, there is no degree awarding standard recognized by the government or relevant institutions, and there is no unified examination and graduation certificate system. Therefore, there is no concept of Gu Weifang's graduation certificate. Weigufang room refers to a traditional processing technology of Chinese herbal pieces.
