It’s true. Four convenience stores in Kunming were accused of selling "fake and shoddy" "Seven Dimensions" brand sanitary napkins, and all the "Seven Dimensions" sanitary napkins sold by the defendants came from the Datong Department Store Business Department in Guandu District, Kunming City. Heng'an (China) Paper Co., Ltd. (hereinafter referred to as "Heng'an Paper Company"), the company that registered the towel trademark, went to court and demanded compensation of 15,000 yuan in economic losses. On the morning of April 19, the Kunming Intermediate People’s Court heard the case in public. Founded in 1985, Hengan Group is one of the first companies to enter the Chinese sanitary napkin market. It is the largest domestic manufacturer of women's sanitary napkins and baby diapers, and its business fields include maternal and child hygiene products and household paper.
