Ten years ago, there was no mobile phone navigation. Although I read the introduction of National Geographic magazine, I couldn’t find this place with the car navigation instrument. I couldn’t ask when I drove to Jingxing County. Now I easily saw the wheel track of Taihang Ramp for more than 2,000 years. Unlike the current road, the higher the paving, the wisdom of the ancients was to cut the mountain stone and bump road for nearly two meters. According to the comrade who had participated in the last county Zhis compilation work today, the last time the road was cut down was about the end of Qing Dynasty and the beginning of the People's Republic of China. It is worth a visit after being used until the end of the year 20.
