With a single phrase from his mother, 'The belly cannot be moxibusted,' Ran Huaizhi remembered it for five years. When his father fell critically ill with a severe white lung disease, he saved his father by moxibusting his back, vowing to make mugwort that his mother could use, and returned to his hometown to found 'Wanran Mugwort.' Eight years later, when the brand grew large, his apprentice Zheng Qiang brought competing products to steal goods, spread rumors, poach technicians and farmers, and counterfeit goods filled the skies. His wife sold their house to pay wages, and his daughter cried on the ridge saying she did not want him to collapse. Refusing to adulterate or lower prices, he signed guaranteed-minimum contracts to invite the farmers back, live-streamed physical ledgers to show the truth, and had his father lift his shirt to expose the moxibustion scars on his back as proof. Zheng Qiang was sent to court, the family returned to the mugwort fields, and they passed down the motto, 'Mugwort must be aged three years, words must be one-tenth real.'
