求与"长江后浪推前浪"对应的英语地道谚语~~~

“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.

Later waves are never weaker than the former.
or
Waves which come later are stronger and higher.
英文的谚语很少有直译的，因为人家那里根本没有长江啊，所以只能用普遍的意思与之对应。
如果还不满意，那就爱莫能助啦:
As in Yangtze River,it's the inferior waves that push the former waves.
