1, spread Buddhism and pray for Tibetans to eliminate disasters. At that time, Buddhism prevailed in the Tang Dynasty, but there was no Buddhism in Tibet. Princess Wencheng is a devout Buddhist. She took pagodas, scriptures and Buddha statues into Tibet and decided to build a temple to preach Buddha. She made goats fill the pond with soil and built Jokhang Temple. After the Jokhang Temple was completed, Princess Wencheng and Songzan Gambu personally planted willows outside the temple gate, which became the famous "Liu Tang" in later generations.

2. Promoted the social progress of Tubo. Princess Wencheng took out five grain seeds and rapeseed and taught people to plant them. Corn, potatoes, broad beans and rape can adapt to the plateau climate and grow well. Wheat, on the other hand, is constantly mutating and finally grows into highland barley that Tibetans like. Princess Wencheng also brought cars, horses, mules, camels and related production technology and medical works.

3. Promote the relationship between the Central Plains and Tubo. After Songzan Gambu married Princess Wencheng, the relationship between the Central Plains and Tubo was extremely friendly. After more than 200 years, there were few wars, and envoys and businessmen exchanged frequently. Songzan Gambu highly praised the Central Plains culture. He took off his felt wool and put it on silk, and sent the children of Tubo nobles to Chang 'an to study Chinese studies. In the Tang Dynasty, all kinds of craftsmen were sent to Tubo to teach various skills.
