Zhang Tong, the grandson of Zhang Liao, a famous general in the late Eastern Han Dynasty, and the son of Zhang Hu. His ancestral home is in Yanmen Ma. Zhang Tong listened to his father's story of the family's history since he was a child, and knew that they were not originally surnamed Zhang, but surnamed Nie. Their ancestor was the Nie family of Yanmen Mayi, who was once a wealthy merchant family.
Because the ancestor Nie Yi offended the Xiongnu family, in order to avoid disasters, a certain generation of the family began to change his surname to "Zhang". Since then, although the family has been passed down from generation to generation, it has not been able to become famous again until the appearance of his grandfather Zhang Liao.
Grandfather Zhang Liao made many military exploits under Cao Cao, and the Zhang family became famous again and glorious. Since he was a child, Zhang Tong took his grandfather Zhang Liao as an example and was determined to glorify the lintel. He trained in martial arts since he was a child, read military books well, and hoped to one day become an excellent general like his grandfather.
Before his father Zhang Hu died, he revealed his worries about the future to his son Zhang Tong. He told Zhang Tong that the Sima family's ambitions were growing and that sooner or later they would replace the Cao Wei regime. He hoped that Zhang Tong would protect the interests of the family and, at the appropriate time, lead the family back to their hometown in the north, Yanmen Mayi, where their roots were and where they could regain their roots.
After Zhang Hu's death, Zhang Tong followed his father's last wish and inherited the title of Marquis of Jinyang. After the fall of the Wei State and the establishment of the Jin Dynasty by Sima Yan, Zhang Tong decided to take action for the sake of the family's future.
After careful planning, Zhang Tong led the family to embark on a journey to the north, embarking on a journey back to Yanmen Mayi, and successfully led the family back to their hometown. After returning to Yanmen Mayi, Zhang Tong and his family began a new life.
In the last years of the Western Jin Dynasty, the world fell into chaos, and the heroes rose together, and the war raged. Zhang Tong occupied the two counties of Lelang and Obibang, and launched fierce battles with Goguryeo in the northeastern frontier for many years. The continuation of the war has left the people of the region exhausted and miserable. Wang Zun of Lelang County began to persuade Zhang Tong to find a peaceful solution to avoid the loss of life.
Wang Zun told Zhang Tong that the current war is not a long-term solution, and that in order for the people of Lelang and the two counties of Daifang to live and work in peace and contentment, they should find a strong backer to ensure the stability of the region. Murong Diao is powerful and attaches great importance to talents, if he can be attached to him, he can not only ensure the safety of Lelang and the two counties of Obifang, but also bring peace to the people.
Zhang Tong decided to accept Wang Zun's suggestion and led more than 1,000 of his people to join Murong Diao. Murong Diao welcomed Zhang Tong's subordination and re-established Lelang County, appointing Zhang Tong as Taishou to manage the area. At the same time, Wang Zun was also appointed to join the army to assist Zhang Tong in managing Lelang County.
