塘中
Before 1744, people of both [[Đàng Ngoài]] (the north) and [[Đàng Trong]] (the south) wore [[áo giao lĩnh|giao lãnh y]] with thường (a kind of long skirt). Both male and female had loose long hair. In 1744, Lord [[Nguyễn Phúc Khoát]] of [[Đàng Trong]] ([[Huế]]) decreed that both men and women at his court wear trousers and a gown with buttons down the front. That the Nguyen Lords introduced ancient [[áo dài]] ([[áo ngũ thân]]). The members of the [[Đàng Trong]] court (southern court) were thus distinguished from the courtiers of the [[Trịnh Lords]] in [[Đàng Ngoài]] ([[Hanoi]]), who wore "áo giao lĩnh" with long skirts. The partition between two families over the country too long so caused the some major differences in Vietnamese dialect and culture between Northern and Southern Vietnamese.
