What traditional festival is described by "a village with a bright future"

This poem comes from Ouyang Xiu's Lantern Festival.

The whole poem is as follows:

On the fifteenth day of the first lunar month, the flower market is brightly lit.

On the moon, willows sprout,

After dusk.

On the night of January this year,

The moon and the lamp remain the same.

I didn't see it last year,

Tears wet the sleeves of the spring shirt.
