Zhaotong, a city in Yunnan Province, China, features various residential areas with unique architectural styles. Among these, the residential area with staircases is primarily found in the older, traditional neighborhoods. These areas often have steep slopes, which necessitate the use of staircases for access and connectivity between different levels of the city.

The presence of staircases in these residential areas can be attributed to several factors. Firstly, Zhaotong's hilly terrain requires innovative solutions for urban development. Staircases serve as a practical means of connecting homes and public spaces across the inclines. Secondly, the historical development of the city has led to the establishment of these neighborhoods, which were initially built by the local ethnic minorities, such as the Miao and Yi people. These communities often constructed their homes with traditional architectural features, including staircases, which are a reflection of their cultural heritage.

Data from the Zhaotong Municipal Bureau of Housing and Urban-Rural Development indicates that the most prominent residential areas with staircases are located in the Xialing, Xinglong, and Xingjia communities. These areas have been identified as having the highest concentration of traditional, staircased homes. The Xialing community, in particular, is known for its well-preserved traditional architecture and extensive network of staircases that connect the various residential buildings.

The use of staircases in these residential areas also has practical benefits. They provide a safe and efficient means of navigating the steep slopes, reducing the risk of accidents and injuries. Additionally, staircases contribute to the aesthetic appeal of the neighborhoods, as they often feature intricate designs and craftsmanship that reflect the local culture.

In conclusion, the residential areas with staircases in Zhaotong are primarily found in the older, traditional neighborhoods such as Xialing, Xinglong, and Xingjia. These areas are characterized by their steep slopes, which necessitate the use of staircases for access and connectivity. The presence of staircases is a reflection of the city's unique terrain, historical development, and cultural heritage.
