Luxi County, Pingxiang City, located at the foot of Wugong Mountain in western Jiangxi, is rich in Eucommia ulmoides, which is known as "plant gold". As precious Chinese medicinal materials, Eucommia ulmoides leaves and Eucommia ulmoides bark have many medical and health-care effects such as tonifying the liver and kidneys, strengthening muscles and bones, lowering blood pressure, and anti-viral. Ten years ago, Pingxiang private entrepreneur Zhang Liming established Jiangxi Galaxy Eucommia Development Co., Ltd. in Yinhe Town, Luxi County, using local resources to develop a series of Eucommia products. After successfully introducing Eucommia tea to the market, Zhang Liming tried adding Eucommia leaves as an additive to feed pigs. It is this intelligent attempt that has created the "Grimmet" green eucommia pork brand that has become famous across the country.

The pig farm is located in the mountains of Yinhe Town, far away from cities and villages. It has a beautiful surrounding environment and fresh air. The pigs drink mountain spring water and eat carefully developed Eucommia feed. The pig brand is named "GREEN-MEAT", which is the English transliteration of green meat.

In May 2008, Eucommia ulmoides pigs were recognized as green food Grade A products by the China Green Food Development Center, becoming the first live pig in the country to obtain green food certification. In October of the same year, "Grimmet" Eucommia pork won the gold medal at the 2008 China Green Food Expo held in Shanghai. Leaders of the national agricultural department and the Jiangxi Provincial Government have inspected the Eucommia pig breeding base many times. At the same time, Grimmett brand pigs have also been rated as famous trademarks of Jiangxi Province, famous agricultural products of Jiangxi Province, and "Top Ten Treasures of Ganpo". In 2014, Grimmett Eucommia pigs were designated by the Nanjing Youth Olympic Games Organizing Committee as the only pork exclusively for athletes. Because the meat is tender, tastes good, is of high quality, is safe, green and nutritious, "Grimette" has been widely sought after since it was put on the market. The products are sold well in Jiangxi, Beijing, Shanghai, Hong Kong, Shenzhen and other places. "Grimette" Pork once sold for a high price of 44 yuan per kilogram in Shanghai and is still in short supply.
