Successive massive Yellow River bursts pushed refugees directly toward death. [What] Han Shantong, Liu Futong and others raised troops against Yuan at Yingzhou under the call of the White Lotus, soldiers binding their heads with red turbans.

It became the ultimate uprising spark that crushed the Mongol-Yuan regime.
