What is the meaning of observing age in Song poetry?

Song poetry was written by Su Shi, which is one of the three poems in Homesick at Dusk.

stay up late or all night on New Year's Eve

If you want to know how old you are, there are snakes going to the valley. The scale is half, who will cover it? The situation wants to tie its tail, although it is diligent and helpless. The child was forced not to sleep and was very happy at night. If you don't sing the morning chicken, you are more afraid of causing trouble. After sitting for a long time, the lights went down and I looked at the Big Dipper. It will be gone next year, and my worries will be in vain. Try to do it tonight, and the teenager can still boast.

Don't get old.

Wealth flies, and poverty feels late. Don't ask if you are late, you can't catch up. Kiss the old man, have a good drink and send him to the north of the world. Although the years are ruthless, the four seasons make me embarrassed. Drinking a glass of wine makes me strong and fat. Be happy this year and don't be sad in the future. Turn around and refuse to care. Don't leave me. The wine column is full of gas. I can't believe it.

Feed this era

The duke of Zhou made a township ceremony without mutual assistance. Ding meat is sent to Zisi, and the finless porpoise is sent out. Making friends is high and low, regardless of size. Since the decline of this ceremony, Ralph has been hungry. The villagers admire ancient customs, entertainment and so on. East and west, just like an ant colony. I would rather not eat or drink than blame each other. Congratulate each other for the Spring Festival and exchange colors for happiness and harmony.
