Interpretation: In the sound of firecrackers, the old year has passed.
Reason: "New peaches for old peaches" describes the scene when everyone is busy taking off the old peach symbols and replacing them with new peaches during the Chinese New Year. Express the meaning of saying goodbye to the old and welcoming the new. The first sentence, "one year old in firecrackers", describes that in firecrackers, the old year is sent away and the new year is ushered in. It is also a scene to bid farewell to the old and welcome the new. Only the first sentence echoes the last sentence.
Appreciate:
The poem "January Day" describes the scene of bidding farewell to the old and welcoming the new in the Spring Festival. Firecrackers sent away the old year, and the peach characters on each door were replaced with new ones. Full of cheerful and positive spirit, which contains profound philosophy, pointing out that new things always replace declining things.
