In the Water Margin, Dai Zong's amazing Taoist skill is: tie two armored horses to two legs and make magical moves, which can travel 500 miles a day; Four armored horses tied to their legs can run 800 miles a day. Therefore, people call it Dai Zong. Therefore, there is a poem saying, "If you are strong enough to chase a swift horse, your shirt will always be dusty, and the skill of defending the Pacific Ocean is amazing. A trip of 800 miles will return at dusk. " These plots are introduced in Chapter 38 "Timely Rain Meeting".
