The LongRun Pu-erh Tea College and Research Institute were built by LongRun Group and Yunnan Agricultural University. We have strong R & D ability. By virtue of this ability, LongRun Group uses the production experience of medicine manufacturing to produce tea; it established a unique quality management system to promote standardized and scientific tea production and specialized processing. It emphasizes on quality control starting from the source. The Group established cooperative relations with millions of tea farmers in Yunnan. Tea farmers grow tea or pick leaves in accordance with the strict standard. This behavior not only ensures the quality of raw materials for LongRun tea, but also provides a solid foundation for Long-Run tea to become a high-quality tea supplier.
