Longci, situated southeast of Tainan, is nestled in the hilly region at the southern end of the Alishan Mountain Range, with elevations ranging from 80 to 350 meters. This varied terrain has fostered a diverse array of natural landscapes. The prevalence of mudstone in the area has led to significant erosion from rainwater and streams, resulting in a distinctive badland terrain known as the barren "Moon World." As a result, many residents have moved away, leaving only around 3,000 people, making it the least populated administrative district in Tainan.

Beimen, located in the northwestern coastal region of Tainan, is the most developed township for the salt production industry in Taiwan. In the past, nearly every household relied on salt production for their livelihood. Today, it has further developed into a major festival that uses salt as a medium.

Located on the Chianan Plain, Guantian in Tainan has a hot and humid climate that is ideal for growing water caltrops, rice, sugarcane, and mangoes. Guantian has the largest area and highest production of water caltrops in the country, earning it the title "The Land of Water Caltrops."
