1. preface

Spring Festival couplet is one of the most connotative elements in Chinese traditional culture. It depicts beautiful images and expresses beautiful wishes with neat, concise and exquisite words. It is a unique literary form in China and an important custom for Chinese people to celebrate the New Year. Every Spring Festival period, whether urban or rural, every household should select a pair of red Spring Festival couplets pasted on the door, bid farewell to the old and welcome the new, in order to increase the festive atmosphere. According to textual research, this custom originated in Song Dynasty and flourished in Ming Dynasty. The earliest Spring Festival couplet that can be checked is "Sanyang began to be distributed, four sequences began to open," which was first found in the cultural relics unearthed in the Sutra Cave of Mogao Grottoes. The couplet was written by Liu Qiuzi of Tang Dynasty and was written in the eleventh year of Kaiyuan (AD 723).

Most programmers of our time are only crude Chinese ink, and calligraphy is basically not good at writing. However, the yearning for a better life was no less than that of literati. With the help of code, we can also write beautiful Spring Festival couplets, and we can also send our most sincere blessings and best wishes to family, neighbors, friends and colleagues.
