What are the warriors Lanling and Princess Lanling in history?

Gao Changgong, the warrior of Lanling, has a wife and a concubine. Chang Gong is the wife of Zheng, the princess of Lanling, and her concubine's name is Wang, whose name is unknown. In order to reward him for his meritorious military service, Jia Hu was ordered to buy him 20 women, but he only accepted one, that is, Wang.

In May (573) of Wuping's fourth year, Gao Wei, queen of the Northern Qi Dynasty, sent an envoy to send Gao Changgong poisoned wine. Gao Changgong said to his wife Zheng, "I am so loyal to my country. Where can I live up to the emperor and give me poisoned wine? " The wife replied, "Why not explain it to the emperor in person?" Gao Changgong asked, "How could the Emperor receive me?" Later, he died of drinking, and his wife Zheng became a Buddha.

It is said that the relationship between the Lanling warrior and the princess is particularly good, otherwise, Zheng would not convert to Buddhism after Gao Changgong was sentenced to death in the Lanling warrior, and the Lanling warrior and his wife Zheng are also deeply affectionate.
