three.
from the end of 199s to the beginning of 2s, Zhao Lin, Li Gongzhen, Li Jingyi and Shang Zhongsheng were known as the four famous mouths of Wuda University (Yi Zhongtian left Xiamen University in 1992).
Li Jingyi has retired. Both Zhao Lin and Li Gongzhen were born in 195s. Only Shang Zaisheng was relatively young (born in 1961). I thought that Zhou Xuanyi (born in 1979) could carry the banner of a new generation of "famous mouth", but I had no choice but to have a knife on his head and be severely cut off.
