Trần dynasty
Short hair or a shaven head was popular in Vietnam since the ancient period. Vietnamese men had shaven head or short hair during Trần dynasty. This can be seen in the painting "The Mahasattva Trúc Lâm Coming Out of the Mountains" which portrayed Trần Nhân Tông and men in the Trần dynasty as well as the Chinese encyclopedia "Sancai Tuhui" from 17th century. The convention was popular until the Fourth Chinese domination of Vietnam.
