Differences:
The feelings between the lines in Wang Guozhen's Farewell are relatively direct. The words "retention", "preciousness" and "friendship" all express their feelings of farewell to their friends, and the full text is fresh, meaningful and catchy.
Li Shutong's Farewell is more subtle, and the full text has a strong classical flavor. It uses images such as "Changting Ancient Road", "Night Wind and Flute", "Sunset" and "turbid wine" to implicitly express the feelings of parting by relying on these images. It is beautiful to read and has a natural feeling.
