Why do Koreans like to write China's calligraphy, but they don't like to write their own country's characters as calligraphy?

1, Koreans (Koreans) didn't have their own writing before15th century, and they recorded their language in Chinese characters.

2. 1443, King Sejong of Korea summoned Zheng Linzhi and other bachelors from Jixian Temple, and according to the phonological structure of Korean and the phonology of China, he created a special text to record the phonology of Korean, which was called Xunmin Andrew. Only then did the official language of Korea appear.

3. Because ancient Koreans had strong ideas of "worshipping Han" and "worshiping Confucianism", learning China's calligraphy became the mainstream of the upper class.
