The Biography of Schiller Part 2(15)

In fact, Zu Ti did not forget the northern expedition all the time. He used the money obtained from trade to prepare military supplies, repaired Huao City, looked around, and built a bulwark, which served as a fortress to protect the land of Yuzhou. But Zu Ti died before the fortress could be built. In the first year of Yongchang (322), Shi Le invaded the south again because Zu Ti was dead. His successor, Zu Yo, could not resist and retreated south to Shouchun. Shi Le then left his troops to settle in Yuzhou, which was again in chaos and entered the sphere of influence of the later Zhao. At the same time, Shi Le also sent troops to invade Xu and Yanzhou. All the troops stationed there in the eastern Jin dynasty had to retreat to the south, and many local dock owners surrendered to Shi.
