How late can I sleep on New Year's Eve?

According to our tradition, we can't go to bed until midnight on New Year's Eve. Why do you say that?

In our country, people have the habit of keeping watch on New Year's Eve. Watching the new year begins with eating New Year's Eve dinner. This New Year's Eve dinner should be eaten slowly. From the time when lanterns are lit, some families have to eat until late at night.

In ancient times, observing the age has two meanings: the old man's observing the age means "resigning from the old", which means cherishing time; Young people keep their age in order to prolong the life of their parents. Since the Han Dynasty, the time for the alternation of the old and new years is generally at midnight. The whole world is looking forward to the arrival of the zero new year.
