On October 16, blogger “Yulie Qige” conducted an undercover investigation of multiple osmanthus processing factories and street stalls in Yangshuo, Guilin, Guangxi, finding large amounts of sulfur powder and sulfur-burning bowls used to fumigate osmanthus outdoors, and said that almost every household in the area is engaged in production. He reported the sulfur raw materials, samples, and video evidence to the local public security authorities, after which law enforcement officers rushed to the scene to crack down on the illegal processing sites and collect evidence.
