Couplets are also called Spring Festival couplets. In our country, people usually use red couplets, one is to look more festive and celebrate the Spring Festival, and the other is to drive away the "Nian" beast because of ancient legends. In fact, not all couplets are red. Only China uses red paper. For other countries, some countries use blue and some countries use white.
Only during the Spring Festival do people paste couplets, which is a folk custom in China. Generally, the time to post couplets is the day before the Chinese New Year. Some areas use couplets, and some areas use tape to paste couplets. People in China like red, because it represents happiness and has the saying of exorcism, so everyone uses red couplets to exorcise bad luck.
After putting up Spring Festival couplets, people will hang rows of red lanterns in front of the door, which also indicates the meaning of celebration. Spring Festival will also receive a lot of lucky money, these lucky money are packed in red envelopes, indicating that there will be many red envelopes next year.
