Shandong is close to South Korea and is the main place for Korean companies to invest in China, such as Qingdao, Weihai and other places. Because the language is similar to Korean, Koreans generally serve as translators, and those with low education are security guards, so Wherever there are Korean companies, there are Koreans. Korean companies in Guangdong also have a large number of Koreans. In order to use Koreans as thugs and manage Han people, South Korean companies generally call them "foreign compatriots" to their faces. These pro-Korean Koreans (perhaps their original intention is to show off to the Koreans) also have a arrogant attitude towards the Han people, saying, "We Koreans, you Chinese..." and call the Han people "Chinese crows" in Korean accent. Han people generally don't understand it. Suffer from being dumb. However, Koreans also look down on the pro-Korean faction behind their backs. In their eyes, it is very interesting for Chinese people to fight against Chinese people (Korean people fighting Han people). They believe that Koreans even bully their own people (Hans), let alone treat foreigners (Koreans) sincerely.
