A few days ago, we followed our divers into the underwater world of Qiandao Lake to enjoy the underwater beauty, before going into the water, the staff set up a seine net on the nearby area, which can block the fish are blocked in the seine net, and it is more convenient for the viewers to observe the fish, the divers went down to dive for about ten meters and encountered a lot of fatheads group of fish, which were swimming in the water at their own pace, and the presence of our divers didn't cause any alarm to them, and the divers were not frightened. Some of the small fish even swam to the front of the camera to show their posture. In the live broadcast, the host also asked the netizens, what are the two cities underwater in Qiandao Lake? In fact, the most famous underwater landscape of Qiandao Lake is He City and Lion City. These two cities in a long time ago, the name of the ancient Chun'an City and ancient Suian City. 1955, because the power sector began to build hydroelectric power plants, Chun'an and Jiande two counties of the residents were transferred to other places, September 21, 1959, the Xin'an River began to cut off the flow of water to the reservoir, since then these two ancient cities and dozens of towns, more than a thousand villages were submerged, sunk to the bottom of the lake. To this day, He Cheng and Lion City has been submerged underwater for more than 50 years, due to these ruins underwater, will not be sand and sun damage, the daily water temperature of Qiandao Lake is generally in the 10-20 degrees or so, so the walls and wooden beams and other architectural facilities have not decayed, are very well preserved. 2001 Tourism Bureau leaders organized the first underwater exploration of the ancient city, divers feel as if they were diving back to the ancient period, as they pushed open the city, the city of the first underwater exploration of the city. When they pushed open the gates, the iron rings and decorations on them were still very clear, and many of the buildings were engraved with age labels. If the view of the fish in the Qiandao Lake was breathtaking, then the view of the ancient city with the divers was even more shocking. We are always curious about mysterious and unknown things, especially the underwater world is even more beautiful, where there is no human wanton destruction, everything is its original appearance, I hope to organize some more of these actions, so that we can explore the beautiful underwater world together.
