When someone accomplishes what the vast majority cannot, it can be called a miracle, and Gao Yang performed such a miracle before many witnesses.
At a distance of one thousand meters, Gao Yang fired twenty shots from his 7.62mm caliber semi-automatic rifle, killing ten people—a fifty percent hit rate.
A fifty percent hit rate might not sound very high, but when a bullet takes two seconds to hit its target, even a slowly moving target can cover two to three meters in that time. Once the opposition realized they were being targeted by a sniper, they began moving constantly, leading to several missed shots by Gao Yang.
However, whether it's operating rocket launchers or machine guns, one must stay put, and Gao Yang's tactic was to target anyone who dared stay in one place for more than two seconds. Thus, although it was possible to dodge a bullet by moving slightly after Gao Yang fired, ten people were still killed after he changed his shooting strategy.
