How tall is Hulao Pass?

Hulao Pass, located in Sishui Town, 65,438+06 kilometers northwest of Xingyang City, Henan Province, is also known as Zhiyi, Sishuiguan and Wulangguan. Legend has it that in the Western Zhou Dynasty, Zhou Muwang hunted here, and the warrior Gao Benrong captured a tiger alive and kept it here, hence the name Hulao Pass. Due to the war and flood, the old site of the pass was destroyed and rebuilt many times. The last restoration was in the eleventh year of Xianfeng in Qing Dynasty. The foundation of Hulao Pass city wall is made of stone, and the city wall is made of loess. At that time, the wall was more than 20 meters high and 10.5 meters wide. However, due to the flash floods, the Great Wall no longer exists. There is only one stone tablet erected in the 9th year of Yongzheng, which is 2 meters high and 0.7 meters wide, and the three Chinese characters "Hulao Pass" are written on it.
