Introduction to the place where General Zuo Quan was martyred: In May 1942, the Japanese army launched an iron wall siege on the anti-Japanese base area in North China. Zuo Quan, deputy chief of staff of the Eighth Route Army, unfortunately died on the Cross Ridge near Matian. The bad news spread to Yan'an, and Commander-in-Chief Zhu was overcome with grief. Jue wrote an elegiac couplet, saying that the famous general would sacrifice his life for the country, and was willing to work hard for our beauty. The majesty of Taihang will be passed down through the ages, and the blood-vomiting flowers will remain in Qingzhang. In 1942, Liao County was renamed Zuoquan County at the request of the people of Liao County.
