On the Chinese New Year, families in China decorate their front doors with poetic couplets of calligraphy written with fragrant India ink, expressing the feeling of life's renewal and the return of spring.
中国过年，家家户户都要贴对联来装饰大门，对联就是用香墨汁写的有诗韵的对子，以此表达万物复苏春回大地之感。
It is said that spring couplets originated from "peach wood charms," door gods painted on wood charms in earlier times. During the Five Dynasties Period (907-960), the Emperor Meng Chang inscribed an inspired couplet on a peach slat, beginning a custom that gradually evolved into today's popular custom of displaying spring couplets.
有人说，春联起源于桃符（周代悬挂在大门两旁的长方形桃木板），门神比春联出现的时间要早。据说五代时(907-960)后蜀国国君孟昶，他突发奇想，让他手下的一个叫辛寅逊的学士，在桃木板上写了两句话（作为桃符挂在他的住室的门框上），由此开始了贴对联的传统，逐渐演变成今天的现如今贴春联，现在贴春联是一个很流行的传统习俗
In addition to pasting couplets on both sides and above the main door, it is also common to hang calligraphic writing of the Chinese characters for "spring," "wealth," and "blessing." Some people will even invert the drawings of blessing since the Chinese for "inverted" is a homonym in Chinese for "arrive," thus signifying that spring, wealth, or blessing has arrived.
除了在大门两侧和上方贴对联外，还会贴一些用中国书法写的“春”，“财”，“福”等字体。一些人会倒着贴“福字”，因为福“倒了”正好和“福到了”同音，意味得福庇佑之意。
