The origin of development:

Couplets originated in Fu Tao, began in the Five Dynasties, flourished in the Ming and Qing Dynasties, and have a history of more than 1000 years. As early as before the Qin and Han Dynasties, in the Central Plains of China, there was a custom of hanging peach symbols during the Spring Festival. Fu Tao, with the names of "Shen Tu" and "Lei Yu" Er Shen engraved on two pieces of mahogany, is hung on both sides of the door to protect the house from evil spirits.

Today's Spring Festival couplets evolved from Fu Tao. The earliest Spring Festival couplets were written by Meng Changjun, the master of Houshu. In the past, he carved the names of two gods, which read "boring New Year, welcome to Qing Yu, celebrate festivals in Changchun", which was also the earliest couplet.

Couplets are the treasures of China traditional culture, and the earliest recorded couplets appeared in the Three Kingdoms period. In 2005, the State Council listed the custom of couplets as the first batch of intangible cultural heritage in China.
