《淮南子·原道训》
九嶷山以南的民众，从事陆地的活少而从事水中的活多，所以这里的民众剪发文身，模仿鱼龙形象；同样只围短裙不着长裤，以便于涉水游渡，着短袖衫或卷起袖子，以方便撑船，这些是由水上生活的特点所决定的。
九疑炎南，陆事寡而水事众，于是民人被发文身，以像鳞虫；短绻不绔，以便涉游；短袂攘卷，以便刺舟，因之也。
The people south of Jiuyi Mountain do less land work and more water work, so they cut their hair and tattoo themselves, imitating the shape of fish and dragons; likewise, they only wear short skirts and not trousers, so as to be able to wade and swim, and wear short-sleeved shirts or roll up their sleeves to make it easier to row boats, which is determined by the characteristics of water life.
