The first sentence said that the fisherman came back from fishing at night and was too lazy to tie the boat;
The second issue shows the place and time of "returning from fishing" and the feeling that the characters are tired and want to sleep but are too lazy to tie the boat. The combination of scenery and scenery shows the carefree life interest.
In the last two sentences, the two related words "even if" and "only in" are released and put away, which pushes the meaning of the poem to a higher level and vividly shows the fishermen's leisurely life interest and the quiet and beautiful scenery of Jiangcun.
