6. Never take the third light from a match, it's bad luck. 不能用同一根火柴点3次火
 

In World War I, snipers sometimes operated at night. Their technique involved waiting for someone to strike a match to light a cigarette; on spotting the light they'd train a scope on them. On the second light, the sniper would focus his shot, zooming in ready for the kill, on the third light, he would fire, killing the person who lit the match.

在一战期间，狙击手通常在夜晚作案。他们的作案技巧就是等有人点烟。第一次点烟时狙击手可以确定方位；点第二根时狙击手瞄准准备射杀；点第三根烟时，他就开火将点火之人打死。
