People from all over the world gather in the land of their ancestors. The northern part of the land of their ancestors is the Longji Ridge. The Longji Ridge is majestic. It starts from the territory of Dan Kingdom in the west, stretches eastward, passes through the northern border of Ciyu Kingdom, and then takes the same force as the Long River in the south of Lingnan to the east for thousands of miles, and then reaches the shore of the boundless East China Sea. Lying like this from east to west, Wei Wei's Longji Ridge has a body of thousands of miles. Longji Ridge does not stop after reaching the East China Sea. It turns to the north and extends in the shape of a dragon's head, which is called Longtoul Ridge. Longtoul Ridge bends along the vast Xiaoxu Bay of the East China Sea and extends to the northeast. After eight thousand miles, it reaches the end of the uninhabited Far North. There may be a sea at the end. Ancient legends say that this frozen sea is the North Sea. Longji Ridge reaches the East China Sea and extends to the south, in the shape of a dragon's claw, which is called Longzhao Ridge. The source of the north-flowing Zu River starts from Longzhao Ridge. Longzhao Ridge goes south along the coast for a thousand miles and then extends into the East China Sea. It then enters the sea five hundred miles to the southeast to form a peninsula, which is the Yuyao Peninsula. The Yuyao Peninsula has few people in the mountains. It faces Dongzhou across 600 miles of Tianyou Bay to the west. Dongzhou and Zhongzhou and Xizhou in the west; Longzhou, Beizhou and Yizhou in the north; Runzhou, Nanzhou and Chuzhou in the south combine to form Hongjiang Kingdom.
