People's Volunteers in a tunnel on the Korean front listen to a musical performance. The singer and musicians are of the Chinese People's Visit Korea to Express Sympathy Art and Literature Troupe (中国 人民赴朝慰问文艺工作团), that visited the front in the spring of 1953. The yellow sign reads "Heroes' Cave" (英雄洞). The Volunteer in the foreground takes an apple from a US soldier's helmet. The poster behind the singer is We warmly love peace, 1952.
