when a wild goose passes,it trails its sound behind,when a man passes,he leaves his footprints ❍ 常言道： “～”。难道匪徒在走过的地方什么也不留？没那事？(曲波《林海雪原》55) As the old saying goes，“When a wild-goose passes,it trails its sound behind; when a man passes,he leaves his footprints.” You mean tosay the bandits could have gone through here without leaving a trace? I don’t belive it.
