When you visit Jiuzhaigou in autumn, the red leaves all over the mountain are more beautiful and bright than the flowers in spring. Green mountains and green waters are colorful, and the snow of cold ling has quietly climbed up the sword rock. Looking around, there is a picture of a fairy's home everywhere, which makes me linger every step of the way. But when it's time to wave goodbye, I want to meet you at the next reunion.
