Princess Wencheng (Chinese: 文成公主; pinyin: Wénchéng Gōngzhǔ; Tibetan: མུན་ཆང་ཀོང་ཅོ, Wylie: mun chang kong co[4]) was a princess and member of a minor branch of the royal clan of the Tang dynasty, who married King Songtsen Gampo of the Tibetan Empire in 641.

[12] Tibetan sources describe Princess Wencheng as “Rgya-Mo-Bzav”, literally meaning “the goddess from the Central Empire”.

[12] According to the Tibetan history, the Songtsen Gampo's and Princess Wencheng's union brought hopes of promoting a harmonious, matrimonial relationship between the peoples of Tibet and China.

[13] Princess Wencheng's life is depicted in texts such as the Maṇi bka' 'bum and the famed historiographies of Rgyal rabs Gsal ba'i Me long.

The third narrative, which was shaped by the Republic of China nationalist discourse beginning c.1928 depicted a "re-imagined" history[16] and image of Princess Wencheng.

The re-imagined image gradually transformed her into a “transmitter of technology.”[12] The seated statue of Sakyamuni brought by Princess Wencheng is enshrined in the Jokhang.

[17] According to legend, Rishan and Yueshan (Riyue Mountain) were transformed by the precious mirror of Princess Wencheng.

Princess Wencheng walked to the dividing line between Tang and Tubo, and threw the Sun and Moon Mirror given by her parents behind her to cut off the endless thoughts of her relatives.

[18] Legend has it that when Princess Wencheng and her party went to Lhasa by way of Chaya, they made a short stop in the beautiful Renda.

The princess used her magic power, just like Sun Wukong, the great sage of the sky, pulling out a few hairs from her head and blowing it on the mountain.
