Couplets

Extracted from the Wikipedia article Couplet.
In Chinese poetry
Couplets called duilian may be seen on doorways in Chinese communities worldwide. Duilian displayed as part of the Chinese New Year festival, on the first morning of the New Year, are called chunlian (春聯; 春联). These are usually purchased at a market a few days before and glued to the doorframe. The text of the couplets is often traditional and contains hopes for prosperity. Other chunlian reflect more recent concerns. For example, the CCTV New Year's Gala usually promotes couplets reflecting current political themes in mainland China.
