South Korea will also post Spring Festival couplets during the New Year. Why are their Spring Festival couplets written in black on a white background?

The main reason is that Korean Spring Festival couplets culture is still different from ours, and the black characters on white background of Spring Festival couplets are also inherited from Korean culture. China's Spring Festival couplets are called "beginning of spring single", "beginning of spring book", "beginning of spring post" and "beginning of spring wish". Korean Spring Festival and China Spring Festival are on the same day. They are all new days in beginning of spring, that is, a new year. People will write their best wishes on the Spring Festival couplets and hope to realize their wishes in the new year. Unlike China's Spring Festival couplets with black characters on a red background, Korean Spring Festival couplets with black characters on a white background.

The time of posting vernal equinox is different. South Korea announced the vernal equinox on the same day in beginning of spring, and it must be announced according to the exact time in beginning of spring. Spring Festival couplets were first discovered in Korea. Spring Festival couplets were first spread by the ruling class in South Korea, but now it has become a folk custom in China. When the Spring Festival comes, local officials will give leaders a five-character poem and choose the best sentence to stick on the pillars of the palace. In Korea, this custom is spread from top to bottom. It was first popular among the royal family and civil and military ministers because they were proficient in Chinese.

In the eyes of Koreans, beginning of spring is the beginning of a year, and it is also a transitional period in a year. If a person wants to be lucky, this day is most likely to change. As soon as they arrive in beginning of spring, Koreans are ready to put up Spring Festival couplets for every household. The most common thing they posted was eight Chinese characters "Happy Spring, Celebrate Jianyang". Although Korean is very popular now, the beginning of the spring post is still written in Chinese characters.

Moreover, Koreans prefer diagonal stickers, similar to domestic seals. Although Spring Festival couplets are only the product of customs, they carry people's expectations for a better tomorrow and become a bridge for cultural exchanges between China and South Korea. Although China and South Korea have experienced ups and downs, their cultural origins are profound.
