Tongtian Cave stretches for thousands of meters, there are no roads, and there are holes in the dark of willows. It seems that through the time tunnel, Tang monks and disciples feel the dangers of traveling westward. They are frightened and frightened, but they also have the joy of overcoming difficulties. The road to the top of the Buddha is forbidden. The mountain road is not repaired. There are many weeds and nobody repairs it. From one step to the top of the Buddha, all the way is to walk on the edge of the cliff, no guardrail protection, dangerous, suggesting that life is critical. Traveling to Batan on Zhonglu Road, the lake is clear and clear. Tourists stop to play and fight, and their fatigue is wiped out. Go up the ladder and go to the source of the journey to the west. Imagine Wu Chengen's view of the Nanfeng Stones. A classical masterpiece begins with his writing and the hard stones become Buddhas. Further north, Flame Mountain came into view, and the palace stones at the foot of the mountain were taken away by tourists as treasures of town houses. Turning upward to the top of the North Peak, a house with a glass door and a triangular thatch roof is built. The windows are expected to overlap with thousands of peaks in the west, green and lush. Out the doors are hills and valleys, near the Baihujian, overlooking Beijing City, with excellent views. Downhill is a 1,000-foot trestle road, sandwiched in two peaks, from then on, climbing up the mountain is also very tough. Generally speaking, 30 yuan ticket is a worthwhile trip to catch up with the discount.
