Fai chun

Fai chun (traditional Chinese: 揮春; simplified Chinese: 挥春; pinyin: huīchūn) or chunlian (春聯; 春联; chūnlián) is a traditional decoration that is frequently used during Chinese New Year. People put fai chun in doorways to create an optimistic festive atmosphere, since the phrases written on them refer to good luck and prosperity. They are customarily written by hand, but for convenience, printed versions are now mass-produced. They may be either square or rectangular in shape. They are popularly used not only in Greater China, but also in Korea, Japan, and Vietnam.
