The correct answer is: they bound their heads with yellow scarves.

The rebel group in the Three Kingdoms period of China was called the Yellow Scarves because they would bind their heads with yellow scarves as a symbol of their unity and rebellion against the ruling powers. The color yellow was associated with the common people, and the rebels believed that by wearing yellow scarves, they could find a leader who would bring them justice and equality.
