This can be said to be playing the edge ball. China's advertising law stipulates that health care products should not promote "curative effect", so some people use this specious language, neither saying that stomach trouble can be cured (illegal) nor eating it (illegal), but using a word like "nourishing the stomach" to promote it. Taigong fishes, and those who wish take the bait! Some people may be willing to be fooled and spend money to raise liars.
