In the 7th century, Songtsan Gampo unified Tibet and established the Tubo Dynasty. According to legend, when Princess Wencheng entered Tibet, it was still a barren beach, and later Jokhang Temple and Jokhang Temple were built here. As more and more people come to worship Buddha, many hotels and houses have been built around Jokhang Temple, forming the embryonic form of the old city with Jokhang Temple as the center. At the same time, Songtsan Gambo expanded his palace in Hongshan (now Potala Palace), so palaces rose up in the Lhasa River Valley Plain, forming a famous plateau city at home and abroad.
Lhasa, located in the valley impact plain at an altitude of 3650 meters, is one of the highest cities in the world. The terrain inclines from east to west. It belongs to the semi-arid monsoon climate in the temperate zone of the plateau, with annual sunshine hours of more than 3,000 hours, so it has the reputation of "Sunshine City". The annual rainfall is 200-5 10 mm, concentrated in June-September, and it rains many nights. The highest temperature is 28℃, and the lowest temperature is-14℃.
In addition to the famous Potala Palace, Jokhang Temple, Norbulingka, the three major temples, Jokhang Temple, Zongjiao Lu Kang, Hebalin Mosque and Chongsaikang, Lhasa has also opened a number of tourist attractions with strong ethnic characteristics, such as temples, hot springs and grassland scenery.
Drepung monastery is the largest of the six gelug sect monasteries, with more than 10,000 monks. Covers an area of more than 20 square meters. The whole temple is large in scale, and there are white buildings with scales and ladders on the mountain, which looks like a lot of rice from a distance, so it is named northern Zhejiang, which symbolizes prosperity.
