Now we know that it is "Zhang's white country". As for Zhang's lineage, according to Gu Zuyu's Minutes of Reading Historical Records, when Zhuge Wuhou went south, he arrived in Baiya, established Longyou as the county chief, and gave him the surname Zhang, so it spread to the 17th century, either as Kunmi, Baiguo or Jianning. During the Zhenguan period of the Tang Dynasty, Wang Zhang sought strength by imperial edict, and the whole country was located in Xinuluo. Hu Weiben's "Nanzhao unofficial history" also said: Emperor Wu of the Han Dynasty, Zhuge Wu, went to Baiya, killed Yong and Min, captured Meng Huo, made the 15th Wang Sunlong the county magistrate, and gave him the surname Zhang. On the 32nd, he was sent for help. In the twenty-third year of Zhenguan reign, Emperor Taizong made him a general. From this calculation, Zhang's lineage is: Renguo (Warring States), Yilong, (Three Kingdoms), and Zhang's pursuit of * * * lasted for 33 generations from Renguo. That is, in 109 BC, Renguo became the king of Yunnan; In 225 ad, the dragon began to accept Zhang's surname; In 627-629, Zhang went to Chang 'an, and was canonized as a satrap by the Tang Dynasty. From BC 109 to AD 629, Zhang sought meditation. The history of the Kingdom of Bai Zi is as long as 738 years, which is even longer than that of Nanzhao Dali.

The Kingdom of Bai Zi should only exist in the hometown of Yunnan-Guizhou Bai people.
