This market, the biggest cardamom market in the area, was already there during the French colonial period and serves as a meeting place for the ethnic groups living in the mountains: Giay, Dao, White Hmong, Hani. Those living in the highlands, like the Hmong and the Zao (Dao) come down to sell their specific products such as cardamom and other spices and mountain plants.

In Mường Hum, you should taste the paddy rice brandy (made with unhusked rice) from the dao village of San Lung. Its fruity flavour and mildness have made it famous well beyond the limits of the Lào Cai province.
