The slightly less famous Huanghuacheng section of the wall is 60 km from Beijing in Huanghuacheng Town. This 10,800-meter section of the wall is the strongest and most well built, with six forts guarding six passes, twelve beacon towers, and thirty-two watchtowers. Ming Dynasty General Cai Kai supervised its construction. So long did it take and so great were the resources he poured into it that the Emperor concluded that General Cai Kai must be embezzling and had him executed.
