The prototype of Wang Zanghai is Wang Zhanhai, a famous Feng Shui master in Ming Dynasty. During the Hongwu period, Mu Ying hired this master to plan the construction and geomantic omen of Kunming. 500 years later, this is the chief designer of Kunming in the south of Yunnan. So these two people should be the same person, but one is a character in the novel and the other is a real historical figure.

Wang Zhanhai and Kunming, Masters of Urban Planning in Ming Dynasty

Mr. Wang inspected the mountains and rivers in Kunming, and the main vein of Kunming is Changchong Mountain, which winds in the north. This mountain has a long history, passing through Dongchuan and Huize in the northeast of Yunnan, reaching Kunming Basin, all the way to Kunming, where it suddenly rises, and the finished glyph tends to wither away, reaching nine liters and nine volts, which is extremely precious in geomantic omen. So Mr. Wang built Kunming into a turtle shape, taking the meaning of mating between turtles and snakes for the benefit of Kunming people.

And buried three stones in the city, the first stone reads: "Yunnan wins Jiangnan in 500 years"; The second stone reads: "After 500 years, the emperors will meet"; The third stone says, "Everything here should take the lead".

This is the only city in China where turtles and snakes mate, yin and yang mate, and heaven and man are integrated and conform to nature.

Kunming urban planning architecture is a masterpiece of urban planning and layout. It takes the form of natural landscape as the starting point and the harmony between individual life and nature as the starting point. It embodies the idea of "imaging in the sky and forming in the earth" in Zhouyi and China's traditional geomantic theory that "a good layout needs both form and spirit".

The geographical environment of Kunming Bazi is surrounded by mountains in the east, north and west, and water in the south and southwest. Therefore, the main body of Kunming City adopts the layout of sitting north facing south, with Dianchi Lake as the open hall of Kunming City. Therefore, the sunshine is more abundant, and the airflow passing through the water surface of Dianchi Lake from the south upper air outlet is fresher.

Because the city is arranged according to the main vein of geomantic omen, Kunming City is backed by the precious purple dragon, which corresponds to the stars in the sky. Let the city of Kunming correspond to the extremely precious pattern of Ziweiyuan, Tianshiyuan, Taiweiyuan and Shaoweiyuan among the four great city walls in The Stars.
