According to historical records, Zhang Gongzi of Zanthoxylum bungeanum became an independent warlord after the success of the uprising and had considerable influence in the northern region. His strength is gradually growing, competing and confronting with other forces. However, with the unification and strength of the Tang Dynasty, Zhang Gongzi's influence was gradually weakened, eventually defeated by the army of the Tang Dynasty and forced to leave the Central Plains.
There is a saying that after Zhang Gongzi left the Central Plains, he went to Hubei to continue the war of resistance. He chose Hubei because the terrain is complex and the mountains and rivers are criss-crossing, which is very suitable for guerrilla warfare. In addition, Hubei is also a place with developed agriculture, which can provide him with food and materials and maintain his power. This answer is made by the net name Feixiang Qishan Tiandi.
In Hubei, Zhang Gongzi established his own base and cooperated with local tribal leaders and warlords. He continued to incite popular uprisings in an attempt to regain lost power. However, the army of the Tang Dynasty besieged him many times, further weakening his strength.
It is said that after several failures in resistance, Zhang Gongzi finally lost the confidence to continue to resist. He felt that he could no longer compete with the Tang Dynasty, so he chose to leave Hubei. As for his specific whereabouts, historical records are not clear, and there is a saying that he fled to Liaodong area.
Liaodong area is located in the northeast, geographically far from the Central Plains, and the mountains and forests in Liaodong area can provide him with good shelter. Moreover, there have been anti-Tang activities in some places in Liaodong, and Zhang Gongzi may have chosen this place to hide.
However, there is no exact record of Zhang Gongzi's specific activities and whereabouts in Liaodong area in history. Zhang Gongzi's characters and deeds spread among the people and became the protagonist of legends and stories. This also makes his real whereabouts more mysterious and unverifiable.
In a word, Zhang Gongzi, a historical figure of Zanthoxylum bungeanum, left many questions and speculations for later generations, and there was no conclusive evidence about his whereabouts. He has a great influence in the history of China, but his final fate and whereabouts may always be an unsolved mystery.
