translation.en: You have to understand about bullets that they go a lot faster than sound, so if someone shoots at you from a few hundred meters, the bullet goes by you, or hits you obviously, half a second or so before the sound catches up to it.
translation.zh: 你应该知道子弹这玩意儿 它飞起来比声音还要快 如果有人朝你开枪 射程也就几百米的话 子弹或者与你擦肩而过，或者击中你 而枪声半秒之后才会传来
