Chinese New Year is an important holiday and is therefore approached appropriately. Preparations start before the holiday begins. You should start with a thorough cleaning of the house to help get rid of evil spirits. You also need to do shopping and prepare gifts for loved ones. Usually, you give them sweets, fruit or money in an envelope. It should be red, because in Chinese culture it symbolizes happiness. The same principle also applies to clothes worn during the holidays - they are usually red or bright coloured. You shouldn't wear anything black or white, these colours are associated with death or mourning. 

After the preparations there is time for celebration. Families gather for traditional meals with jiaozi dumplings. They also participate in fireworks shows. Various performances such as lion and dragon dances that bring good luck are also popular.
