Introduction to "Sacrificing Yourself for Your Country": South Korea Jun has been paying attention to the development and changes in Sino-Japanese relations. In mid-September 1940, Han Guojun came forward to convene celebrities from all walks of life in northern Jiangsu to participate in the joint anti-Japanese symposium held in Hai'an. He later made a lot of contributions to uniting forces to resist Japan. In 1941, he was trapped in the Japanese occupation but remained unyielding. He died suddenly in sorrow and anger early the next year.
