1. When a person crosses the New Year's Eve, he should find a threshold, hold his watch in the last few seconds of 22, count down to 3.2.1, and jump over this threshold at the last second, so that he can establish a sense of New Year's Eve ceremony and cross all the thresholds in 221.

2. Friends who like cooking should bake a cake for themselves when they are alone in the New Year's Eve, and write Happy 221 on the cake! In this way, I can establish a sense of new year's ceremony, step into 221 in the sweet taste of cakes, and stay sweet in 221.

3. When friends wandering alone in a strange city spend the New Year's Eve alone, they should take a hot bath on the last day of 22, turn off the lights on the evening of 31st, play slow romantic music in the dark, count the past of 22 carefully and look forward to the future of 221, which is also a good way to celebrate the New Year's Eve.

4. Don't treat yourself badly when you are on New Year's Eve. Treat yourself to a delicious meal on the 31st night, which will make people feel happy. If you are full, you will be able to have plenty of food and clothing in 221.

5. If a person doesn't want to do anything during the New Year's Eve, he should find a favorite movie to watch, help himself to stick to the zero point, count down in his mind at the zero point, and shout out "I'm coming in 221" at the first second of 221, so that he can face 221 with confidence.
