During filming, director Cheng Hao and starring Liu Yunlong had an "artistic argument" about the script. In the play, he plays two roles and has three identities-a Japanese spy Gao and an identical producer agent. Many Russian people's actors (equivalent to China's first-class actors) were used in "meritorious works", and the famous Japanese actor Hatae Ao was invited by Japanese senior general Sakahara. The whole play used more than 3000 Russian extras. Merit invited Bruce Law, a famous Hong Kong special effects director, who has produced the special effects team of Mission Impossible and directed films such as Hot Men and Police Story 3. At the beginning of the whole play, the shooting of the Soviet army chasing the Japanese spy Gao and his son in the snow was completed in 12 days after the crew braved the cold of MINUS 30 degrees in Linhai, Heilongjiang. Gong Gong tries to restore the historical truth at that time to the greatest extent. The reason why Harbin was chosen to shoot is because Harbin is known as the "Oriental Moscow" and has a strong Far East style; Clothing is also the military uniform and casual clothes of the Soviet Union and the Japanese army during World War II. It was specially bought from Japan and processed completely according to historical records. In order to restore the war scenes at that time, the crew set up the "Lindong Fort" and the "Marubei Gun", which is known as the first in Asia, after consulting a large number of historical materials and field trips between China and Russia, and truly restored the Lindong Fort in the northeast at that time. Marubi Cannon alone cost 300,000 yuan. Miniature cameras, transmitters and special knives used in espionage are all real instruments.
