Keeping the Lunar New Year's Eve is one of the most important activities, and the custom of keeping the Lunar New Year's Eve has a long history. The earliest record can be found in the Local Records of the Western Jin Dynasty: on New Year's Eve, all parties give gifts to each other, which is called "the year of giving back"; Wine and food are invited, which is called "not old"; Young and old get together to drink and wish a complete song called "age division"; Everyone stays up all night, waiting for dawn. This is the so-called "shou sui".

On New Year's Eve, the whole family get together, eat New Year's Eve, light candles or oil lamps, sit around the stove and chat, wait for the time to bid farewell to the old year and welcome the new year, and keep vigil all night, which symbolizes driving away all evil diseases and epidemics and expecting good luck in the new year. This custom gradually became popular. At the beginning of the Tang Dynasty, Li Shimin, Emperor Taizong, wrote a poem "Shou Sui": "Cold words and winter snow, warm with spring breeze". To this day, people are used to celebrating the New Year's Eve.
