National Day early, less than 9 o'clock to arrive at the parking space for election, 12 o'clock out to see that the parking space is very full and difficult to find... The Great Wall is very small. It's an enemy building in a few steps. It's too pediatric for us from Beijing. At the time of abandonment, the stone steps that need to be climbed up by only one person are very steep. The height of each stone step is different. The span of each stone step is 40 or 50 centimeters. It can only climb up by pulling the railings. The legs ache for 2 days. Finally, it reaches the top with difficulty. The descent is even steeper and almost vertical. Everyone can only hold the handrails on both sides and move down sideways. Few people can go down directly without their hands. They can no longer underestimate it. They even have some awe and reverence for the ancient builders. Every step seems to fall on their sweaty backs... Although tired, it's worth it!
