The full moon is characterized by rising and falling with the sun, appearing at dusk and disappearing in the morning!
Since it is a full moon, it goes without saying, on the fifteenth or sixteenth day of the lunar calendar!
In this poem by Ouyang Xiu, it is the Lantern Festival. Last year's Lantern Festival, the flower market was as bright as day. The moon rose to the willow tree, and he met me at dusk. Ouyang Xiu's description of the meeting of lovers at midnight has become a masterpiece through the ages and a well-known poem.
