Changzhou Huayu Biotechnology Co., Ltd., formerly known as Jurong Jinfeng Chemical Plant, located at the west foot of Maoshan Mountain, was founded in 1987. Mr. Ni Jinzhong, the founder of the first generation, adhering to the entrepreneurial spirit of "pioneering and inspiring the mountain forest", has gradually formed a production and management model focusing on "naphthalene series" plant growth regulators in the past ten years. The vivid image of the older generation of Jintan Chemists who are modest, pragmatic, innovative and conscientious has become the epitome of China's economic development from the 1980s to the late 1990s.
