Lung-tan Shiang has great conditions for growing tea trees. It is elevated and slightly inclined, has a high temperature, sufficient rainfall, and red soil. Ever since the Ching Dynasty, farmers here have planted and exported tea making tea and rice are the most important agricultural products here.

Lung-tan produces green-leaf Oolong tea. Farmers process this tea into white Oolong tea, which is known as "Oriental beauty" to westerners. During the 1960s and 1970s Lung-tan's tea roduction was at its peak. The amount of tea fields and production were higher than ever. The export was high as well. As tea prices were cut in recent years, Lung-tan is losing its advantage. So the amount of tea fields are decreasing, as well as the quality. A decade ago, the government assisted that tea farmers manufacturer tea by machine, and helped the farmers to plant higher quality of tea trees bringing about a higher level of technique in tea-manufacturing .

The Governor of Taiwan in 1983, Teng-hui Lee, named Lung-tan's tea ;Lung-chuan pao chung tea.; Since that time, Lung-tan's tea has had an official name. There are around 900 hectares of tea fields in Lung-tan Shiang. When you pass through the suburb area, you can see the tea trees arranged in a manner to facilitate the machine harvesting of tealeaves. Pipelines are set up between tea trees to water the trees. Besides the commercial production of tea, local people integrate this local industry and tourism into the unique tourist tea gardens .
