Jade Lake, the Jade of the Imperial City.
When Zhongzhou city was first established, there was no water to drink in the city and No Way to Make a Living.
The person who built the city broke the rocks on the ground and dug a huge pit. Three days and three nights later, he opened a channel that connected the water of the West Ocean and led the surging water into the city. The water circled the city and finally poured into the city, glittering like a Jade belt. Jade Lake.
For thousands of years, the water of the Jade Lake entered thousands of households through several channels. Along the way, there were countless flowers and Willows. When the water flowed and the flowers fell in spring, the half-moat of spring water bloomed the city's flowers, and the misty rain darkened the thousands of households. It was praised by the later generations and conferred by the Emperor as the Jade of the Imperial City.
