Firecracker peach symbolizes vigorous solar terms.

"Firecrackers ring like the old year, and peach blossoms are exchanged for thousands of families for the New Year." It's a pair of Spring Festival couplets. This was originally based on Wang Anshi's poem in the Northern Song Dynasty: "In the sound of firecrackers, except for one year old, the spring breeze sends warmth into Tu Su. Thousands of families always change new peaches for old ones every day. " Consists of ...

This couplet was also changed into a six-character couplet in the early days of liberation: "With the sound of firecrackers, the pink is new."

The modern "peach symbol" does not refer to the "peach board", but refers to the Spring Festival couplets in red paper and ink. The "update" of the next couplet can also be changed to "welcome the new" or "welcome the new".

Wang Anshi's poem "January Day": "Firecrackers make one year old, and spring breeze warms Tu Su. Thousands of households always exchange new peaches for old ones. " "Tu Su" is probably a kind of grass similar to Artemisia argyi, which the ancients thought could exorcise evil spirits. The wine soaked in this grass is called "Tu Su wine". Tongya Plant said that during the Sui and Tang Dynasties, Sun Simiao, a famous doctor, had a recipe for Tu Su wine. In the ancient Chinese New Year, the youngest drank first and the oldest drank last, which may mean paying attention to new forces. Therefore, Su Dongpo's poem says, "But when you are drunk, you can be full of worries and drink Tu Su." . In modern times, the Japanese still drink Tu Su, and Tu Su extended his life. They said that Tu Su Fang was a prescription of Hua Tuo, a famous doctor in the Three Kingdoms, including Saposhnikovia divaricata, Atractylodes macrocephala, Platycodon grandiflorum, Cinnamomum cassia, dried tangerine peel and so on.
