Beijing South Second Ring Road departs at 6:00 a.m. via Jingshi-Langzhuo-Zhangshi Expressway, 420 kilometers round trip, 150 yuan high-speed, the highway is smooth and very good to walk. However, there are many tunnels along the Zhangshi Line with a speed limit of 60. 8.30 to the scenic parking lot. After carrying lunch and four bottles of mineral water, I went back from the south line to the middle line for more than eight hours. Start at 18 p.m. and return to Beijing at 20.40 p.m. Ticket 150 per person, parking fee 5 yuan, actual fee 10 yuan. The overall environment in the park is very good, and there are not many people. Many places are still under construction. Workers have a hard time carrying things to the mountains. Under the mountains, the sun is blue, the sky is white, and sunscreen should be paid attention to. It's raining at the top of the mountain. It's cold! A disposable raincoat of 5 yuan can not withstand the wind and rain, it will burst in a moment! Glass trestle road charges 5 yuan per person, because the rain is blurred and not alarmed. Driving for a day is very enriching.
