Gongguan is a simple Hakka rural town. Agriculture is its major economic output. In addition to perilla, red date, taro, and preserved mustard are regarded as the “three treasures of Gongguan.” The perilla plum presented by Gongguan Farmers’ Association is made with local perilla, which flourishes there, and the plum grown in Xinyi Township. Joining these two famous local agricultural products, they are preserved in the traditional Hakka method. Each is round and tasty, in beautiful color. No wonder it is consumers’ favorite. Moreover, it is a popular commodity in Gongguan Township.
