The Potala Palace, a landmark in southwest China's Tibet Autonomous Region, features a mural that illustrates a historic marriage between the Han and Tibetan ethnic groups.
The mural depicts ancient Tibetan officials standing in a row, holding their hands in front of their chests, to welcome Wencheng, a princess of the Tang Dynasty (618-907). The princess traveled to Tibet to marry Tibetan King Songtsen Gampo in the 7th century.
Similar to the mural, many other relics in Tibet have helped further uncover cultural communication and integration between the plateau region and the rest of China.
