Introduction to Zoumaquan: The Heavenly King's City has six gates: Chaoyang Gate, Shuixi Gate, Shizui Gate, Kala Gate, Tower Gate, and Zoumamen. Zoumamen is the mountain gate with the gentlest terrain. This gate leads to a village below - Shenmen Valley. It was also the passage for the king to transport grain and grass to the mountain. Originally there were 6 drinking mangers side by side, and the horses transporting grain and grass were here. This rest is named Zouma Spring.
