What is the background of Wang Anshi's writing January 1?

This poem was written when the author first worshipped the Prime Minister and started his New Deal. 1068, Shenzong called Wang Anshi to "go to the right again and again", 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 same year, during the Spring Festival, Wang Anshi saw that every household was busy preparing for the Spring Festival, and associated with the new atmosphere at the beginning of the political reform, he wrote this poem with emotion.
