1. Geographical location: West Sichuan refers to the west of Sichuan, including Ganzi, Aba and Ya 'an, which is located in the east of the Qinghai-Tibet Plateau and connected with the Sichuan Basin. Lhasa, located in the central part of the Qinghai-Tibet Plateau and on the north side of the Himalayas, is the capital of Xizang Autonomous Region at an altitude of 3,650 meters.
2. Cultural background: Western Sichuan is a multi-ethnic settlement, in which Tibetan, Qiang, Yi and other ethnic minorities have profound cultural connotations, retaining a large number of traditional cultures and customs. Lhasa is the center of Tibetan Buddhist culture. Temple palaces such as Potala Palace and Jokhang Temple are representative buildings of Tibetan Buddhist culture.
3. Historical background: Western Sichuan was a part of Tubo Dynasty in Tang Dynasty, the territory of Xixia State in Song Dynasty, the Ministry of Foreign Affairs of Sichuan in Ming Dynasty and the western border of Sichuan Province in Qing Dynasty. Lhasa, the capital of the Tubo dynasty in the Tang Dynasty, was one of the six Tubo departments in the Ming Dynasty and became the center of the integration of politics and religion in Tibet in the Qing Dynasty.
In a word, Western Sichuan and Lhasa are different in geographical location, cultural background and historical background, but they are both important representatives of minority cultures in China, with strong humanistic atmosphere and unique natural scenery.
