Tosu Lake is also known as Yuyou Lake, and it is also an inland lagoon. The lake reflects the blue sky and white clouds, so beautiful that it is not necessary. Get off the bus! Take pictures! Just got off the bus, and a bunch of mosquitoes rushed out around to chase people and bite. This is the most proactive mosquito I have ever seen, and the fighting force is very strong. These mosquitoes are probably the patron saint of Tosu Lake, afraid that outsiders trample the beauty of the lake, can not fight to death can not drive away!
