Why is there an underwater city in Qiandao Lake?

He cheng was founded in 208 AD. Under the ancient coin-shaped "Shang"-shaped porch, pieces of Huizhou mansions were built according to the flow. Another lion city is named after Wushi Mountain in the north of Sui 'an County. Since the Tang Dynasty, this city has been regarded as the government of Sui 'an County, and was called "Little Tianfu in West Zhejiang" in ancient times. These two ancient cities were once the hubs of Shang Hui Road along the Xin 'an River.

Half a century later, Xin 'anjiang Hydropower Station gradually retreated to the East China standby power station and gradually faded out of people's sight, followed by the reputation of Qiandao Lake as a tourist attraction. It is difficult to find a complete ancient city pool on land after historical events such as "breaking the four old buildings" and rebuilding the old city. Thousand-year-old underwater city Qiandao Lake was remembered at this time.

Under Qiandao Lake, there are two thousand-year-old cities sleeping: he cheng and Lion City. According to historical records such as Annals of Chun 'an County, from June 5438+0955 to June 5438+00, the then Ministry of Electric Power Industry built Xin 'anjiang Hydropower Station at Tongguan, the junction of Chun 'an and Jiande. On September 2 1, 1959, the Xin' an River was cut off and the reservoir area began to store water. Since then, these two counties with a long history in western Zhejiang have quietly "sunk" into the bottom of Qiandao Lake. 20 1 1654381on October 7th, the ancient city was rated as a provincial cultural relics protection zone. 20 1 1 In February, China National Geographic magazine published a group of exquisite photos of ancient underwater cities, which once again ignited the enthusiasm of all walks of life to pay attention to ancient underwater cities.
