Explore the ancient city of Guangyuan(4/5)

Guangyuan is an ancient city in northern Sichuan that is home to preserved towns, precipitous mountains and meandering rivers. It is one of the best tourism cities in China. With the ancient name of "Lizhou", the history of Guangyuan dates back to 2,300 years ago. Guangyuan has abundant tourist resources, many of which precede even the empress. The best-known site is the Sword Gate Pass, a towering V-shaped mountain pass, which gave rise to the household Chinese idiom, "One man at the pass keeps 10,000 men at bay." [China.org.cn]
