Time: August 7 (lunar July 7)

Feature: According to the legend, the festival is held to commemorate the couple Nguu Lang -Chuc Nu (also called the couple Ngau) who love each other very much but can’t live together because Chuc Nu is a fairy in the heaven and Nguu Lang is a buffalo boy. They lives separately on the two banks of the Galaxy and are allowed to meet each other once every year thanks to a bridge called “O Thuoc” built by the crows and magpies. In each meeting, they usually weep for joy and their tears turn into rains, called “Ngau” rains.
