Princess Jinching (金城公主, 699-740) was the great-granddaughter of the Emperor Gaozong and the Empress Wu Zetian. She was adopted by the ruling Emperor Zhongzong.
During peace negotiations between the Chinese and Tibetans, it was agreed that she would become the bride of the Tibetan emperor in a marriage alliance between the two powers. In 710, she departed Chang’an, the capital, accompanied by the Emperor Zhongzong to a city he later renamed Jinching in her honor. She was 10, 12, or 16 years old at the time, depending on the source.
The young princess continued on escorted by a Chinese general. And the trip would take them to the furthest reaches of Tang China, through Yumen Pass, named for the many jade caravans that passed though the fortress wall. The spot is dry, often windy, and in the summer scorched by heat.
The wind howling through the gate makes a mournful sound.
When the young princess reached Tibet, the Tibetans convinced the Chinese general escorting her to recommend that China cede the border land of Qinghai, home to the Qiang people. It was supposed to be a bathing fief for the princess but hostilities between the two countries continued and the area became a staging area for Tibetan attacks on China.
The princess’ life in Tibet was not a happy affair. In 723, she requested asylum with the King of Kashmir, but was dissuaded from going. She remained active with the Chinese community in Tibet, was responsible for building temples, and continued to correspond with her adopted father, the emperor.
After the princess’ departure, the emperor, saddened by her leaving, ordered that poems be written on her behalf.
Wang Zhihuan responded with the beautifully written “Beyond the Border”.
