Judging from Yuan Zhen's five poems of parting thoughts, it means that people who pass through the sea will see other water instead of magnificent water. After seeing the clouds in Wushan, I think the clouds in other places are not worth seeing. The extended meaning is: I only have eyes for you, and only you make me unforgettable.
(2) Willing to unite as one and never give up.
From Zhuo Wenjun's "White-headed Song", the original meaning: I thought that if I married a single-minded man, I could fall in love and be happy forever. But now most people understand that to win a person's heart and love each other to the end.
(3) Life is worse than death.
From the biography of jing yuan in the Northern Qi Dynasty, "A gentleman would rather die than surrender!" "It is better to be a broken jade than a full tile", that is to say, it is better to let the jade pieces be broken than to let the mud tiles be preserved. People often use this idiom to mean that they would rather die than surrender. Sometimes it is also described as unwillingness in love.
