Well, I just saw your question. With my research on Korea and Japan and my research on the history of Korea and Japan, I can accurately answer you:
Both Japanese and Korean are pinyin characters, and each symbol has a fixed pronunciation and does not express meaning.
In the Tang Dynasty, Japan borrowed the radicals of Chinese characters and created katakana, which is generally used to phonetic Chinese characters. Hiragana was founded by China calligraphy to record Japanese pronunciation. Since it is called a pen name, its real name is Chinese characters. Japan later simplified Chinese characters on a large scale, and now it is like this, circulating under the pseudonym * * * *. The pseudonym is the same as China's pinyin. Children usually learn to write their own names under pseudonyms first, and then learn Chinese characters one by one in senior grades.
1443, Korea borrowed Chinese characters to create a kind of phonography, which is now Korean. At that time, it became a "proverb" with false meaning. Content words are Chinese characters. 60% words in Korean are similar in pronunciation to Chinese, and can be written in traditional Chinese characters, which are called "Chinese characters" in Korean. After the Korean War, Li Chengwan, who hated China, ordered the abolition of Korean characters. It was not restored until 2003. Koreans, like Japan, know many Chinese characters only by advanced intellectuals.
Japanese, Koreans and Koreans must use Chinese characters for their names. I didn't know the name of the crown prince of North Korea before. According to the pronunciation, South Korea writes it as Kim Jong-un or Kim Jong-un. Later, the North Korean government released information, published Chinese characters, and wrote "Kim Jong-un". For this reason.
