Photos of Songliao Bianguan Gu Tunnel

In ancient times, Xiongxian County was called Xiongzhou. It was a frontier fortress in the Northern Song Dynasty and a battleground for military strategists. Today, there are many war relics in Xiongxian County, among which the ancient tunnels of the Song and Liaoning borders are typical. During the Northern Song Dynasty, this was the junction of Song and Liao. It is said that Yang Yanzhao, a famous general of the Northern Song Dynasty, guarded here for 16 years without losing an inch of land. Xiongxian County is located in the plain area, and there is no danger on the battlefield. Yang Yanzhao has won many battles, which is not unrelated to the tunnels he built at that time. Since 1964, blue brick structures have been discovered successively in Qigang, Guzhuangtou and Xing Village in Xiongxian County due to irrigation and soil borrowing activities. Experts have identified them as underground passages used for military defense in Song and Liao Dynasty. Tunnels have three uses in the military: one is to hide and transport troops; the other is to transmit information quickly; the third is to monitor the enemy's situation with acoustic principles. Sauce-glazed jars, projectiles, and iron arrowheads have been unearthed in ancient tunnels.
