Henan | The earliest established stronghold in Chinese history

❤Reason for recommendation: Hangu Pass was first built in the Zhou Dynasty, guarding the throat of Xiaohan, it is the ancient gateway to Chang'an in the west and Luoyang in the east, and is the earliest established stronghold in Chinese history. 'Named for its location in the valley, as deep and dangerous as a box', during the 3000 years of its establishment, many famous battles took place here, which had a profound impact on the course of Chinese history. 👍Most recommended: During the Warring States period, Duke Xiao of Qin seized the land of Xiaohan from the Wei state and set up Hangu Pass here. Hangu Pass is easy to defend and difficult to attack. After the rebellions in various places at the end of the Qin Dynasty, King Huai of Chu announced that whoever entered Guanzhong first would be the king of Guanzhong. The 'pass' referred to here is Hangu Pass, which shows the military importance of Hangu Pass. 🌟Highlights: The original pass tower was burned down by Xiang Yu, the Overlord of Western Chu, and has been repeatedly built and destroyed, and no longer exists. The current pass tower was built in 1992 according to the image of 'Hangu Pass East City Gate' on the Han Dynasty painted brick unearthed from Qingyang Palace in Sichuan, and is a retro-style building imitating the Qin and Han Dynasties.
