Gao Yang shot at the leg of the soldier who rushed out, then immediately fired a second bullet at the soldier's hand, worrying that the soldier might shoot after being shot, so it was safer to take the gun down.
Gao Yang's shooting speed was too fast, so the consequences of firing two shots were not much different from firing just one; anyway, after the soldier fell to the ground, the large group of people in standoff around him did not immediately start shooting.
Firing a shot is very dangerous; in such a standoff, if someone suddenly fires, it is likely to cause everyone to shoot simultaneously, which would be truly dangerous.
If it weren't for hearing Mr. Lavagani shout not to move, Gao Yang wouldn't have fired his gun, but after Lavagani shouted, the situation became slightly better; at least those Iranians wouldn't fire immediately upon hearing gunshots.
