为什么春节期间要贴年红？

A long time ago in China, there was a scary monster (怪兽). Its name was “Nian”. Every year, Nian would come on the first day of the new year. It ate animals and people. People were worried.

One day, people found out that Nian was scared of red. Everyone began buying red things. They bought red clothes and lanterns. They hung red lanterns and red spring couplets (春联) on doors and windows. After that, Nian never came back.

Now, during Chinese New Year, people still buy lots of red things.
