Khau Vai Love Market is a unique and unique love market in Vietnam. This is not a commercial fair but a place where people meet, talk and interact with each other. The fair is from the legend of a couple who is in love but cannot come together. Fair is open once a year starting from the evening of March 26 of the lunar calendar.

On the evening of the 26th, the villagers set up the fire and start organizing the fair. People singing, dancing, and drinking together all night long. By the morning of the 27th when the party was over, every couple said goodbye to each other in regret.
