是英语俗语,很经典：
“长江后浪推前浪,世上新人换旧人”英语可以说成：
“As in the Yangtze River waves urge waves,so the younger generation excels the older generation.”
或者：长江后浪推前浪,一代更比一代强（As in the Yangtze River,the waves behind ride on the ones before,The new generation excels the old.）
即：“青出于蓝而胜于蓝”英语这么说：
Indigo blue is extract from the indigo plant,but is bluer than the plant it comes from.
山外有山,天外有天
There are mountains beyond mountains,and heavens beyond heavens.
山重水覆疑无路,柳暗花明又一村
A sudden glimpse of hope in the dark mist of bewilderment,it`s a long lane that has no turning.
