I stopped arguing with Chinese people a looooooooonnnnggggg time ago because it's a waste of time and energy, most of them are not science literate to the most basic level. Whenever one of them says something inaccurate, especially stupid beliefs like "mixing hot and cold food will kill you" or "Chinese bodies are different" I smile, nod and move on. I kinda feel sad for them, a life of ignorance and superstitions. The logic of science doesn't apply to NongGuo.
