What emotion did Wang Anshi express when he wrote Yuan Day?

"January Day" describes the exciting, joyful and moving scene of the New Year's Day, and expresses the author's thoughts and feelings of political innovation.

This is an impromptu work about welcoming the New Year in ancient times. Based on folk customs, it sensitively absorbs the typical materials of ordinary people during the Spring Festival and captures the representative details of life: setting off firecrackers, drinking Tu Su wine and changing peach symbols, which fully shows the joyful atmosphere of the New Year Festival and is full of rich life breath.

"Firecrackers are one year old, and the spring breeze warms Tu Su." Setting off fireworks on New Year's Day is an ancient custom that has continued to this day. In ancient customs, every year on the first day of the first month, the whole family drank Tu Su wine, and then wrapped the dregs in red cloth and hung them on the doorframe to "exorcise evil spirits" and avoid the plague.

The third sentence, "Every family lives", inherits the previous poems, which means that every family is bathed in the light of the early spring sunrise. The last sentence describes the forwarding discussion. Hanging peach symbols is also the custom of the ancients. "Always replacing new peaches with old ones" is a sentence pattern of compression and ellipsis. The new peach omits the word "character" and the old peach omits the word "peach", so they are used alternately because of the limitation of words per sentence.
