The third night of the Chinese New Year is also known as the Night of the Wedding of the Mice. The are lots of Chinese folk and orchestra music that celebrate this specific event and the music are some of the nicest to listen to!
On this night, people go to bed early and all the lights in the house are switched off so as not to disturb the Mice on their weddings. Some people also leave out some new year candies on the floor for the wedding :-)
Actually, after a week of frantic activities, it is nice to go to bed early and have a good rest. With all the lights out, no visitor are likely to turn up!
