Crisis in the late sui dynasty

There are Zhai Rang and Shimi crock rebels in Henan. In the 12th year of Great Cause (6 16), Zhai Rang, at the suggestion of Shi Mi, broke the fortress of Di Chin Pass (now Xingyang City, Henan Province) and laid the foundation for Xingyang counties. In the first year of Yining (6 17), Wagangjun captured Xingluocang, a grain depot in Luoyang, the capital. Zhai Rang gave way to Shi Biao because he was good at fighting.

Shi Biao calls himself Duke Wei, with the country name Wei, and lives in Luokou, Luoyang. Later, they occupied Luocang and arrived at the gates of Luoyang. But internal suspicion made Shi Biao kill Zhai Rang and others, and finally surrendered to Yang Dong, the king of Yue.

There is an insurgent army in Dou Jiande, Hebei. In the 12th year of Great Cause (6 16), Dou Jiande led Hebei rebels to all parts of Hebei and occupied parts of Jizhou, Hebei Province. Two years later, he became Emperor Xia. At the same time, Gao Tansheng and Gao Kaidao were also detained in Hu Airong and Yuyang, Hebei respectively.

Du and Fugong are stronger in Jianghuai area. In the ninth year of Daye (6 13), he transferred soldiers and rebelled in Qixian County (now Shandong Province), and then went south to the south of the Yangtze River. In the first year of Yining (6 17), Gaoyou was occupied and Jiangdu (now Yangzhou City, Jiangsu Province) was cut off from the north. Du calls himself the general manager, and he has a long history with Fu Hongyou.
