Dissolved fresh water is blue as moss, and the wind is calm in bloom. I don't know where the boat is carrying this autumn stream. Head-up is smooth sailing. What does this poem mean?

In early autumn, the water is as green as moss (because of water chestnut). The autumn wind is quietly blowing those water chestnut flowers. I'm afraid they brought this autumn color to the foreign guests cruising in the boat.

There are several disadvantages,

First of all, "Rongrong new water" is a remarkable dynamic of river flow, which is contradictory to the feeling of "calm water" behind it.

Secondly, the author's first two sentences are surprisingly similar to someone's poem.
