The specific time for keeping the year old is: New Year's Eve, which is also "New Year's Eve".

This day is a day for people to eat, drink, play and have fun. Northerners make dumplings, and southerners make rice cakes. The shape of dumplings is like "Yuanbao" and the sound of rice cakes is like "Nian Gao", which are both good omens of good luck and good luck.

The custom of staying up late on the New Year's Eve not only expresses a feeling of nostalgia for the passing years, but also expresses good hope for the coming New Year. The ancients wrote in a poem "Shou Sui": "Invite the Ajong family to keep the year old, and the wax torch passes red to the blue gauze. Thirty and sixty years have passed by, but I cherish my years from this night." It is human nature to cherish the years. Therefore, the great poet Su Shi wrote the famous line "Keeping the New Year's Eve": "There will be no time next year, and worries will be wasted; if you work hard today, you can still be proud of your youth!" This shows the positive significance of keeping the year old on New Year's Eve.
