Yunlong Mountain is good. First of all, you have to find out whether you get off at Xuzhou East Station or West Station, usually at East Station. You can take a taxi to the north gate of Yunlong Mountain at the railway station, which takes about 15 minutes, 10- 12 yuan. Go up the mountain from the north gate, 20-30 minutes to the mountain, and stay on the mountain for no more than 40 minutes. You can see yunlong lake near Shanxi, and you can also shorten your time in the mountains. Before 3: 30 to 4: 00, it takes 7- 10 minutes to take a taxi to yunlong lake at the north gate. Yunlong lake is very big, and there is a small South Lake in the south. I suggest you go there. The time to play there is up to you. There is a general hotel nearby, 100- 150 yuan. Different hotels have different specialties. If you don't eat there, you can take a taxi to Gupeng Building, which takes about 10 minutes. There is KFC and McDonald's, and the charge is 10- 12 yuan. After eating, take the 1 bus to the nearby East Railway Station every 2-3 minutes. There is another train at 10 in the evening, and the time is 10 minutes. It takes about 10 minutes to get to the station by taxi at KFC, and the cost is about 10 yuan. It takes about 3 hours to finish the rough tour of yunlong lake in Yunlong Mountain from the mountain.

If you want to go to Yunlong Mountain, the bus number is 1 1, which is in the north of the station square. Every 2-3 minutes. You don't have much time, so I suggest taking a taxi
