Folk Lantern Festival customs. Popular in Fujian and Taiwan. Folklore. On the fifteenth day of the first lunar month, the heavenly official (blessed god) wants to look at the lamp. In the old days, the unmarried girl and the married but unborn daughter-in-law were invited to string lights in the lantern group in the evening, hoping to meet the god of happiness. The girl prayed to find Ruyi Langjun as soon as possible, and the daughter-in-law prayed to have children at an early date. Now the custom has become a simple entertainment custom.
