I haven't read many books, but the one I remember the most is "Love is a Barren Flower Garden" written by Zhang Miaomiao. The beginning of the book says - "Stories are lessons. People who have read them should not live like them." I opened the book again, and I still like this sentence very much.
After appreciating every interesting "story", we will reminisce with enjoyment: some are smiling, some are angry, and some are imagining what we would do if we were the person in the story... But no matter what we do, we are never the people in the story, we are just others...
