There are many legends associated with the name Bai Chay. According to one legend, when the fleet carrying food for the Yuan-Mongolian invaders led by Truong Van Ho came there, the Vietnamese troops and locals under the leadership of Tran Khánh Duset fire to it. The whole fleet was engulfed in fire. Meanwhile, the northeast wind blew hard and further added fuel to it. Fire was so fierce it burned down the forest in the western side of Cua Luc. Hence the name Bai Chay.
Another legend has it that the western side of Cua Luc used to be a wharf for seagoing boats. Acorn-barnacles firmly attached to these boats’ sides and underneath, and might wreck the boats. The local population had to use casuarinas leaves to burn acorn-barnacles. From Hon Gai and other neighboring places, people always see a blaze from there, so they called it Bai Chay
