What is the festival of Spring Festival?

"The sound of firecrackers is the sound of a new year, and the spring breeze sends warmth into the tassel" means "Chinese New Year", that is, the first day of the first month of the Chinese lunar calendar, which is a quotation from the poem "The Day of the New Year" written by Wang Anshi of the Song Dynasty. The full poem is as follows:

Wang Anshi, Song Dynasty, New Year's Day

A year of firecrackers, the spring breeze sends warmth into the tassel,

A thousand doors and ten thousand tels, always change the new peach for the old one.
