The clear Lingxi River comes from the north, like an elegant jade belt. On the bank of the green and silky Lingxi River, there is Laosicheng, "the giant town of five streams" and "the gloomy border town for hundreds of miles". According to the "Yongshun County Chronicle", Lao Sicheng, referred to as "Sicheng", also known as Fushi City, was the political and cultural center of the Tujia people in western Hunan in the past dynasties. From the fifth year of Shaoxing in the Southern Song Dynasty (1135) to the fourth year of Yongzheng in the Qing Dynasty (1727), Laosicheng was the administrative seat of the Yongshun Tusi regime and the political, military, economic and cultural center of the Tujia people in western Hunan. After 23 generations of chieftains' continuous and meticulous construction, it has a glorious and prosperous history of nearly 800 years.

Laosicheng was built on an extremely steep mountainous area, close to mountains and rivers. The only channel to communicate with the outside world is the wooden bridge on the Lingxi River. It is easy to defend but difficult to attack, achieving a perfect combination of natural terrain and military defense. Perfect blend. For 800 years, Laosicheng has always been a lonely and carefree city. This is due to the special political system of ancient China, the chieftain system - feudal dynasties in the past dynasties ruled the local people by enfeoffing local hereditary leaders of ethnic minorities. In addition to paying tribute and collecting corvees, the chieftain king was responsible for all military and political affairs. The Tusi Dynasty enforced the ban that "Barbarians are not allowed to leave their caves and Han are not allowed to enter". The Tusi King was hereditary in the family, passed down from father to son or direct brothers. No matter how the central dynasty changed, the chieftain king in Laosi City always lived a gorgeous life. Just as the Qing Dynasty scholar Peng Shiduo described in his "Bamboo Branch Poems": "There are brocade nests in Fushi City, water waves beside Tuwang Palace, thousands of red lights, thousands of people, lingering and waving hands and singing."

Laosicheng is divided into Neiluo City and Wailuo City have four city gates in the southeast, northwest and northwest. The city has cobblestone pavement and eight streets and nine lanes crisscrossing it. There are not only many buildings such as the Jinluan Hall and the Purple Mountain Cemetery, but also cold caves, hot caves and secret chambers all over the ground for the chieftains to enjoy themselves. In its heyday, Laosicheng was densely populated, so there are records in history books of "three thousand households in the city and 800 outside the city." With the great changes of "returning from the soil to the locals", as time goes by, although Sicheng has lost its former glorious and spectacular style, the Ancestral Hall, Jade Emperor Pavilion, Lion Bell Bell, Dezheng Stone Stele, Yinan Archway and other buildings still retain their charm. …….
