1360 years ago, Princess Wencheng bid farewell to Chang 'an, the prosperous capital of the Tang Dynasty, and married Songzan Gambu, the king of Tubo. This story about the marriage between Han and Tibet not only opened a new chapter in the ethnic relations between Han and Tibet, but also brought more developed technologies such as medicine, textile, calendar, paper making and pottery making to the snowy plateau through the virtuous Princess Wencheng, which promoted the development of Tibet, and Princess Wencheng was therefore loved by the Han and Tibetan people. Up to now, portraits and statues of Princess Wencheng can be seen everywhere in Tibet Museum, Jokhang Temple and Potala Palace. The traditional Tibetan opera Princess Wencheng has been staged again and again, and people often tell her story in novels, poems and oral literature.
