Jingnan stronghold, the site of the Tusi of Tangya from the Tang family

The Tusi city of Tangya began to be built in the early Ming Dynasty. After hundreds of years of wind and rain, it witnessed the whole process of the Tusi system from its heyday to its demise, and is a gem of the Tujia ethnic group's historical culture. In the 1980s, a chance archaeological survey unveiled the mysterious veil of the Tusi city of Tangya. Through meticulous excavation and in-depth research of the site, experts revealed its profound historical background, and in 2015, they helped it successfully be listed on the World Cultural Heritage List, making the Tusi city of Tangya shine brilliantly again. The current site of the Tusi city of Tangya has been well protected and managed. The city walls, the site of the yamen, the group of tombs, and the majestic stone archway still stand tall, showing the world the appearance of the former Tusi dynasty. The slogan 'Jingnan Stronghold' engraved on the archway is majestic, demonstrating the authority and glory of the Tusi era, and also implies the important historical position of the Tusi city of Tangya in maintaining border stability and promoting ethnic integration.
