Trumpeter in position. Who is the prototype of the Four Elders?

The archetypal figures of the Four Elders in The Trumpet in Place are four first-class military chiefs of the Rocket Army. The writers changed their names to the names of four elders in the play, namely Lang Yongcheng, Cheng Haofeng, Wang Xianmin and Hou Jidong, all of whom are veterans of the Rocket Army.

The four elders in the play have their own characteristics. Lang Yongcheng is a driver trumpeter. He is the only person in the whole brigade who can drive a missile transport vehicle of more than 20 meters. He can not only drive, but also operate other trumpeter positions.

Cheng Haofeng is a very powerful trumpeter. The Rocket Army has always had a legend about him. As long as he doesn't nod, no missile can enter the combat troops. Anyone who encounters problems in the operation process can ask Cheng Haofeng to solve them.

Wang Xianmin has the title of Mr. Feng Shui. He is in charge of the spare warehouse. He will adjust the ventilation device and be familiar with every corner of the spare warehouse. Hou Jidong has launched three missiles and made great contributions, so there are four elders in the rocket army, and there are prototypes in reality.
