Bian Zhi Lin's appreciation out of context should be short! ! !
The analysis of "certainty" means "you stand on the bridge and see the scenery". The "you" here is undoubtedly looking at the "scenery" from a subjective point of view, which has certain "certainty" or "subjectivity"; In the poem "Bright Moon Decorates Your Window", the "bright moon" exists for you or for you, and the "you" here is undoubtedly definite or subjective. Obviously, the first sentence of the two paragraphs in the poem shows a certain "happiness". The second sentence of each section is the analysis of "certainty". The certainty and subjectivity you got in the first sentence were made relative and objective by these two poems, and the joy of certainty turned into relative sorrow.
