Why do Chinese slogans appear in U.S. military bases in South Korea?

The Osan base in Gyeonggi Province, South Korea is an outpost for the United States to monitor North Korean missile launches. The U.S. soldiers here have a slogan, "Fight tonight" (Fight tonight), and put this slogan on on the wall, probably to boost morale. In the newsreel broadcast, we can see that under Fight Tonight, there are four Chinese characters: Always on the battlefield.

Chinese characters are the ancient carrier of Korean. Therefore, when learning Korean, you must first fully master Chinese characters and know the meaning of the original Chinese characters to be marked. Until the 1960s, Chinese characters were a compulsory course for middle school students in Korean schools. However, after the 1970s and 1980s, the government gradually 'abolished' Chinese characters. Now the Korean government requires the full restoration of Chinese characters, which also proves the all-encompassing nature of Chinese culture.

Chinese civilization is the parent civilization of South Korea, North Korea, and even Japan. After they spread and merged, they became the sub-civilizations of East Asia. The child sub-civilizations must be similar to the parent civilization. If they are not reconnected with the Chinese parent civilization, Korean, Korean, and even Japanese will all become dried, soulless cultural mummies!
