简介：Now, there are more than 40,000 soldiers and horses beside the canal, as well as 40,000 civilians. Including the 6,000 new troops brought by Yuan Jixian, there are nearly 50,000. However, civilians could only help dig trenches and build fortifications, but they could not help guard the river. Guarding the canal still had to rely on 40,000 official troops. Wu Di believed that 40,000 people would be difficult to stabilize the canal defense line.
