In summer, Jiuding Mountain in Maoxian County has an unforgettable beauty. Summer resorts around Chengdu. Beginning in mid-June, wild flowers are competing, gray peaks and green grass flowers everywhere, and a mirror-like black dragon pool and white dragon pool, which combine into a texture painting that is only available in a movie. Luckily at night, I enjoyed the prelude to the Leo meteor shower, and suddenly felt that I had found the meaning of life.
