Many cultural sites of different historical stages have been found and excavated in Tibet, such as the Neolithic Age and the Tongshijing Age. In 1979, the archaeological excavation of the Changdu Karuo Site in Tibet was a historical site of 4000 to 5000 years ago, and many ancient cultural sites were also found and excavated in Nielamu, Dingri, Shenza, Linzhi, Motuo and other areas. This shows that there were human beings living and multiplying in Tibet from 7,000 to 20,000 years ago. In Tang Dynasty, Tibetan hero Songzan Ganbu unified the Qinghai-Tibet Plateau and established the Tubo Dynasty. In 710, Princess Wencheng of the Tang Dynasty married Songzan Ganbu, which made the Tubo Dynasty and the Tang Dynasty maintain friendly relations in politics, economy and culture.
Tibetans have their own clothing, calendar, etiquette, food culture, festivals, architecture, etc. They also have their own unique language and writing, which shows that Tibetan culture has a long history. Tibetans generally believe in Tibetan Buddhism. Buddhism was introduced to Tubo from Tianzhu in the seventh century A.D. and has a history of more than 1400 years. The Tibetan people have created a splendid national culture, leaving a very rich cultural heritage in literature, music, dance, painting, sculpture, architectural art and so on. In addition, Tibetan opera has its own characteristics, and Tibetan medicine is also an important heritage of mankind.
