Wang Anshi in Yuan Dynasty [Song Dynasty]

The roar of firecrackers, the old year has passed; The warm spring breeze ushered in the New Year, and people happily drank the newly brewed Tu Su wine.

The rising sun sheds light on doors of each household, New peachwood charm is put up to replace the old.

Translation:

The old year passed with firecrackers, and Tu Su wine was enjoyed in the warm spring breeze.

The rising sun shines on thousands of families, and they all take down the old peach blossom symbols and replace them with new ones.

The introduction and appreciation of this poem was written at the beginning of Wang Anshi's New Deal. In order to get rid of the political and economic crisis faced by the Song Dynasty and the constant intrusion of Liao and Xixia, 1068, Song Shenzong summoned Wang Anshi to "turn to the right repeatedly", and Wang Anshi immediately wrote to advocate political reform. The following year, he devoted himself to politics and presided over the political reform. In the New Year of the same year, Wang Anshi wrote this poem in association with the new atmosphere at the beginning of the political reform.

Poetry is an impromptu work to greet the New Year in ancient times. Based on folk customs, it sensitively absorbs the typical materials of ordinary people during the Chinese New Year, and grasps the representative details of life: setting off firecrackers, drinking Tu Su wine and changing peach symbols, which fully shows the happy atmosphere of the Chinese New Year and makes life colorful.
