The Can Cau market is a bustling weekly event held every Saturday in Si Ma Cai District, Lao Cai. Located just a mile from the Vietnam-China border, it takes a significant effort for people to get there. Despite this, the market attracts thousands of people who travel there to trade, meet, and find love. The market is a melting pot of minority ethnic groups, including the Red Hmong, Nung, Phu La, and Chinese people from across the border. The market offers a wide range of goods, including fabrics, livestock, and local corn wine. The market is particularly famous for its buffalo trading section, where you can find buffaloes of various types and sizes.
