On the eve of the Spring Festival, every household will paste up on doors a spring couplet written on red paper to give a happy and prosperous atmosphere of the Festival. In the past, the Chinese usually wrote their own spring couplets with a brush or asked others to do for them, while nowadays, it is common for people to buy the printed spring couplets in the market. They are usually posted in pairs because even numbers are connected with good luck and auspiciousness in Chinese culture. 在大年三十晚上，家家户户都会在门上贴上用红纸写的春联，传递出喜庆热闹的节日气氛。 在过去，中国人常常用毛笔自己写春联或者是请别人写春联，而现在，人们习惯购买市场上印刷好的春联。 春联通常是成对张贴。因为双数在中国文化中是好运和吉祥的象征。 本文来源：https://www.wddqw.com/doc/21c4c45b453610661fd9f459.html
