What is the meaning of the ancient poem of the night light on the fifteenth day of the first month?

From the Tang Dynasty poet Zhang Hu's "Night Lights on the fifteenth day of the first month", the original text: Thousands of doors are unlocked and brightly lit, and moved to the imperial capital in the middle of the first month. Three hundred wives danced in sleeves and wrote the sky in an instant.

On the Lantern Festival, thousands of families go out of their homes, and countless lanterns light up in the street, as if the whole Kyoto is shaking. Countless ladies-in-waiting sleeve dances, the joy of singing and dancing on earth rose to the sky.

This poem describes that everyone has gone out, people go to the empty building, enjoy themselves, and then return to the Lantern Festival scene, which is the most poetic and soul-destroying moment.

The custom of burning lanterns in the Lantern Festival began in the Han Dynasty, and in the Tang Dynasty, the activities of enjoying lanterns became more prosperous. Lights are hung everywhere in palaces and streets, and tall lantern wheels, towers and trees have been built. According to the folk tradition in China, people light thousands of lanterns on this bright night to celebrate. Going out to enjoy the moon, lighting and setting fires, enjoying lantern riddles, eating Yuanxiao, family reunion and celebrating festivals are all enjoyment.
