The vast Tianliao has many rivers and hills, so the farming space is limited. Besides, its rugged terrain such as that in the Moon World causes water shortage. However, local residents know how to maximize use of the land to grow many kinds of vegetables and fruits, jujube, longan fruits, bamboo, banana, etc. Among these, banana has the biggest production volume with excellent quality, so Tianliao has become a major banana exporting region.
