How to play the prelude, paragraph change and ending of the guitar "Orchid Flower"?

These two symbols mean that the middle part needs to be repeated.

The prelude to this song is the first two sentences (the two sentences without lyrics).

If we change the passage, we will start from the second paragraph after singing "No Bud (note that there is a sustained sound here:-)", and "A lot of colors will be added" from "Suddenly Autumn to ……", but it will end in a high note here.
