This is a classic Sichuan tour itinerary combining nature, humanities and interactive experiences, involving highland areas (Jiuzhaigou, Huanglong), plain cities (Chengdu), and mountainous scenic spots (Mt. Emei), and experiencing the change of landscapes from high altitude to low altitude. It is suitable for first-time visitors to Sichuan, especially travelers who wish to experience the essence of Sichuan in a limited time.
