原本是古长江的河床。

Used to be the bed of Yangzi River.

距今300万年前，长江流域西部地势进一步抬高，东西两条古长江终于贯通一气，浩浩荡荡流入东海。

Eventually, by 3 million years ago, the western part of the Yangtze River Basin has risen to such a level that the river was flowing eastwards to eventually empty into the East China Sea.

就是这条长江最大的支流，奔腾着，传唱着这首流传千古的沧浪歌。

It is the river, the biggest branch of Yangzi, flowing with the song of CANGLANG from one generation to another since the remote time.
