A major clan, To (), brought the name Tuen Mun to the area. They migrated from Jiangxi on the Chinese mainland and established a village Tuen Mun Tsuen () late in the Yuan dynasty (1272–1368). As more and more villages were established, the village was renamed Tuen Mun Tai Tsuen (), which means "large village" in Chinese. As yet more villages were established, a market town of Tuen Mun Hui () (now Tuen Mun Kau Hui) was established. This town lies where present-day Tuen Mun Kau Hui is situated.
