The custom of posting Spring Festival couplets in Korea originated from our country. In our country, when happy events happen, red is the main color, because it represents celebration. However, in the long history of our country, before the Han Dynasty, it was not only red that represented happiness, but white that represented happiness. When Koreans accepted this custom, it was just before the Han Dynasty. With the development of society, this custom in Korea has never changed. It still uses white and black paper to write Spring Festival couplets.
South Korea was founded later than China, that is, after the demise of the Shang Dynasty, it moved to the Korean Peninsula, so many Korean folk cultures followed the Shang Dynasty. With the continuous development and progress of society, these cultural rules have been well passed down in North Korea. So in their eyes, white is not auspicious, on the contrary, white is festive. Therefore, during the Spring Festival, they will put on white Spring Festival couplets and then put on traditional costumes to worship their ancestors.
With the development of network technology and frequent international communication, people can easily find cultural differences between countries. Only by respecting the cultures of other countries can we better understand the reasons for cultural differences. In any case, in the eyes of Koreans, the purity represented by white is a color of positive energy. Therefore, before asking questions, it is best to know enough to avoid unnecessary misunderstanding.
