Li Chen, the author of Waterfall Couplet, wrote the whole poem: A thousand rocks and valleys spare no effort, and you can know the source from a distance. Can the stream stay? After all, the sea is a wave. The latter two means refusing to stay in the stream, moving on, flowing to the sea, and deciding to turn into rough waves.
The first two sentences of this poem describe the extraordinary waterfall experience and high weather, describe the most prominent characteristics of its character, and are full of pride at the same time, which makes full preparations for the latter two sentences. The third and fourth sentences express the author's spirit of being ambitious, not afraid of difficulties and not giving up until he reaches his goal.
