Jilin Nong'an Processing Facility was built in Nongan County, Jilin Province, Northeast China, in May 2000. Starting from April 2003, the Changchun base continues Gaorong's quality service under a new name: Changchun Gaorong Agriculture Co., Ltd. Changchun Gaorong Agriculture Co., Ltd. has a total investment of 11 million Yuan RMB. The Changchun base covers 27,000 square meters and is equipped with a refrigerated warehouse covering 3,100 sq. meters. This base has land covering a total of 1500 acres and 100 green houses, where it grows snow peas, sugar snaps, broccoli, spinach, cabbages, onions, carrots and yams.

The annual production capacity is up to 7,000 tons.
The climate of the region where Changchun base is located is classified as "Mid Temperate Zone Continental Climate."

The region has an average annual temperature of 4.7 C, an average annual rainfall of 510 millimeters, an average 2590 hours of sunshine and 145 frostless days. The fertile soil mainly consists of blackland, meadow soil and chernozem. In the summer of 1999, Gaorong took advantage of the local geography and climate to start trial-planting snow peas, sugar snaps, broccoli and spinach, products that were out of season in many other areas of China around that time.

This counter-seasonal vegetable planting technology proved successful and was implemented on a large scale by Gaorong in 2000, making it the first time that Chinese producers offer the international market the above four kinds of vegetables in large quantities during the summer months. Until now Gaorong still maintains its leading position in the supply of counter-seasonal vegetables among its Chinese competitors.
