When the Soviet army fought the Japanese army in Yamakaji, the fierce fighting ignited a fire, and the mountains were burned red for several days and nights. Yamakaji was thus remembered.
One day in August, 20 12, Liu Lailin, a villager from Liumao Village, Muling Town, Muling City, accidentally discovered the remains of Soviet Red Army martyrs on the burning mountain near the village. On May 15 and 12, the "First Sino-Russian Joint Search for the Remains of Soviet Martyrs Sacrificed in China" was held. Chinese and Russian search teams conducted a one-month search for the remains of Soviet martyrs in Yamakaji, Muling Town, Muling City.
