After the Yellow Scarf Army was suppressed, there were many peasant rebels in Hebei, such as Zhang in Boling (now Lixian), Chu Feiyan, Huanglong, Zuojiao and Baique in Changshan, with numbers ranging from 20,000 to 30,000. They attacked cities, plundered land and fought against government forces. In the second year of Pingping in Hanzhong (185), Zhang and Chu joined forces to attack pottery, and Zhang was killed in the middle stream and returned to Chu. There are many people who claim to be millionaires, called the Black Mountain Army. Later, Cao Cao surrendered to the Braque Mountain army and got more than100000 sergeants.
