Introduction to the high-foot team: Transportation "Mainly by waterway, supplemented by land" is Kangwanwan's flexible method to invigorate the circulation of goods, and the high-foot team is its main measure for water and land transfer. When the Kang family's fleet passed through the Sanmen Gorge, the terrain was difficult and they had to pass through three passes: the human gate, the divine gate, and the ghost gate, so the Kang family formed their own team of mules, horses and stilts. The Kang family was engaged in cotton and cloth business with the Qing army in Shaanxi. They took advantage of the Qing army's suppression of the White Lotus Sect and supplied the Qing soldiers with food, cotton and cloth for ten years. At this time, the Kang family reached its peak. In the middle of the Qing Dynasty, after the Kang family's fleet transported goods to the dock, they had to go through land transportation, which required manpower and vehicles. The Kang family formed its own high-foot fleet, which increased the transportation capacity, shortened the round-trip cycle, and improved The credibility of the fleet was enhanced, and at that time it was possible to operate both by land and water.
