Lions King Hi-Tech  (301305. SZ) was founded in 2001 and is committed to becoming a world-class intelligent biotechnology enterprise. At present, it is a leading enterprise in the biotechnology resource utilization of biomass waste in China, and is listed as one of the "Top 70 Innovative Enterprises in Shenzhen" along with Huawei and DJI.

Since its establishment, Langkun Group has focused on cultivating new quality productivity and achieving long-term goals of high-quality development, driven by technological innovation. Based on the same technology platform - the Bio Intelligent Manufacturing Comprehensive Innovation Center, it has developed two main businesses: "biomass resource regeneration" and "synthetic bio intelligent manufacturing". Langkun Group has built industry-leading biotechnology experimental platforms, including high-throughput and high-sensitivity droplet microfluidic platforms, gene construction platforms, high standard molecular biology laboratories, and bioengineering laboratories. It has established core technology groups such as biological fermentation technology, biological separation and purification technology, enzymatic technology, and HMOs (human milk oligosaccharides) biosynthesis technology, with multiple technologies leading domestically.

In 2023, Zhongke Langjian, a subsidiary of Langkun Group and an independent brand of human milk oligosaccharides (HMOs), was officially established. Zhongke Langjian is committed to utilizing self-developed and industry-leading strain genetic modification technology, high-intensity fermentation process and other synthetic biology technologies to promote the research, development, production and sales of high-end health products such as HMOs. It is one of the first enterprises in China to achieve industrialization of lactose-N-tetrasaccharide (LNT) and lactose-N-neotetrasaccharide (LNnT) in HMOs, and the purity of the produced tetrasaccharide and neotetrasaccharide products reaches the international leading level, with specifications reaching the industry's best standards.
