Why is TCM valued in Korea?

Koreans attach importance to the maintenance of traditional culture, and Huangdi Neijing has become a compulsory medical subject there since the Tang Dynasty. Learning Huangdi Neijing is the first step to consolidate the foundation of traditional Chinese medicine, and the doctors there have a solid foundation of traditional Chinese medicine and can flexibly use traditional Chinese medicine treatment methods, and the treatment effect is obvious. And we in China are busy making money these years, and Huangdi Neijing is only an elective course. The foundation of traditional Chinese medicine now cultivated is not solid. Anyone who knows how to inject will do so regardless of taboos, and a couple who can prescribe drugs will prescribe more than 20 kinds of drugs. Many drugs don't care if they can't be put together, and they don't follow the rules at all. There are no traditional culture classes in primary schools, and most of them recite the three-character classics. They just want to recite the text without profound meaning. Traditional culture has become a decoration, and many people don't understand it.
