The prototype of Lei Suisheng in the battle of Changjin Lake was Kong Qingsan in Jinan, Shandong Province. But Kong Qingsan can only be regarded as one of Lei Suisheng's archetypal figures, because the director concentrated many stories of revolutionary martyrs on these figures when shaping them. Lei Suisheng is called Lei Gong in the film, and the soldiers also respectfully call him Lei Dad. Lei Suisheng is the oldest in the whole company. In Wu's notebook, Lei Suisheng was ranked on the first page, and he was the only soldier who survived on the first page.

Lei Sui introduced the instructions.

Lei Suisheng is not only a living fossil of Qilian, but also a clown of Qilian. Wu Liqian asked Lei Gong to take care of his brother Wu Wanli. Lei Gong plays with Wu Wanli all day, and Wu Wanli likes to play with Lei Gong, too. This old and young scene brought too much joy to the audience. Although Lei Suisheng mocked Wu Wanli on the surface. In fact, he knows quite well. He loves Wu Wan Li and regards Wu Wan Li as his own son.

It's a pity that such a lovely father Lei died in the first part of Changjin Lake. At that time, Lei Suisheng got into a jeep with a marker bomb to disperse the air bombing of the US military. Ignoring the pain caused by the white phosphorus bullet, Lei Gong drove a jeep to distract the enemy plane, but he was hit by a bomb and died heroically.
