On every Sunday mornings, Pa Co fair market takes place like a small weekly festival to the ethnic people here. Pa Co Market is where you can witness the customs and habits of Hmong culture. Lying between Mai Chau and Moc Chau, Pa Co Market is the meeting point of two ethnic groups: Hmong from Moc Chau and Thai from Mai Chau. The bustling atmosphere of the market is so special compared to the quiet feeling of the weekdays. People will bring their self-made and self-grown products trying to sell to others. Pa Co Market is one of the unique things to do in Mai Chau.
