During the journey, I visited many old streets. Langzhong in Nanchong, Jinli in Chengdu, Yingxiu in Wenchuan, and my favorite is Huanglongxi, happy with its water and rhyme. A Yellow Dragon stream crosses the street, sometimes turbulent, sometimes soothing, which adds a lot of romance and poetry to the old street. It's really cool in the hot summer. Various gestures of green plants can be seen everywhere, swaying posture. The tall and gloomy ancient banyan trees, the ancient buildings at the cornices and flying corners, and the complete ancient yamen are all describing its ancient history, displaying a unique flavor, while the dazzling commodities and mouth-watering delicacies make people feel the richness and beauty of living in the present. If you can come here for a few days, a pot of tea, simple clothes, life will be tasty.
