What kind of person is Wang Zi who lives in Yin Shan, Wang Ziyou?

Wang Ziyou (338-386): Han nationality, whose real name is Wang Huizhi, was born in Linyi (now Linyi, Shandong) in the Eastern Jin Dynasty, and was the fifth son of the great calligrapher Wang Xizhi. This man has neither peerless talent nor great achievements, and his moral character is even more lacking. It seems that he can't touch any of the "three immortals" pursued by the ancients-virtue, merit and standing. However, he was born in a famous family, and his personality was uninhibited, quite like a scholar in Wei and Jin Dynasties. His deeds can be found in Shi Shuo Xin Yu written by Liu Yiqing in the Southern Dynasties.
