Dazhao Temple, located in the center of the old town of Lhasa, is a Tibetan Buddhist temple built by Songzan Ganbu, the Tibetan king. The reason why Lhasa has the reputation of "Holy Land" is related to this Buddha statue. The temple was originally called "Lhasa" and later became the name of the city and evolved into the current "Lhasa". After the completion of the Dazhao Temple, it was revised and expanded repeatedly in Yuan, Ming and Qing dynasties to form the present scale. The circle of Sakyamuni Buddhist Hall around the inner center of Dazhao Temple is called "sack outline", the circle around the outer wall of Dazhao Temple is called "eight outlines", and the street radiated out of Dazhao Temple is called "eight outlines street" or octagonal street. Taking the Dazhao Temple as the center, the Potala Palace, Yao Wang Mountain and Xiaozhao Temple are included in a large circle called "Lin Ge". The three rings from the inside to the outside are the routes of the Tibetan people's ritual of traveling through Buddhist scriptures. The Dazhao Temple, which combines Tibetan, Tang, Nepalese and Indian architectural styles, has become a thousand classical models of Tibetan religious architecture.
