Yunlong Lake is known as the sister lake of West Lake. At the foot of Yunlong Mountain, it is not far from Xuzhou Museum. These scenic spots can be arranged to travel together, beside which there is a bus stop, which is very convenient. My route is Xuzhou Museum - Yunlong Mountain - Yunlong Lake. Because of the snow, I went up the mountain from the north gate of the Museum to the top of Fanghe Pavilion. I went down the mountain directly from the west gate and went out for five minutes. The area of the lake is very large. There are many scenic spots such as Liu Beiquan, Han Portrait Stone Museum, Art Museum, Bath, Bonsai Garden and so on. There are hiking roads around the lake, which is convenient for the residents of Xuzhou to keep fit. There are few visitors to Yunlong Lake in early winter. It is expected to take more than two hours to walk along the lake. Look at the lake's wide surface. At that time, just after the snow, the distant mountains, near the green water, along the coast pavilions, there is no turning over the mood.
