How to introduce the custom of Spring Festival in English?

The customs of the Spring Festival in English are as follows:

In China mythology, a monster named Nian will come out to hurt people on New Year's Eve, so people get together and stay up late to chat, hoping to spend their time peacefully. The custom of staying up late (Chinese: keeping the old age) symbolizes avoiding all diseases and disasters and wishing good luck in the New Year.

In China's mythology, a monster named Nian will run out the night before the New Year to harm human beings, so people get together to chat, hoping to spend the night safely. Therefore, people in China call the custom of staying up late on New Year's Eve "guarding the old age", which means to stay away from illness and pray for good luck in the new year.

The first day of the New Year in China, also known as "Chicken Day", officially begins at midnight.

At midnight, people officially enter the first day of the New Year, which is also called "the golden rooster announces the dawn".
