Cancer prevention is a big topic. We have a lot of anti-cancer propaganda, especially now there are many anti-cancer foods and fruits. I don't think this kind of publicity is appropriate. This anti-cancer is a systematic project with strong comprehensiveness. Doesn't mean that eating a food can fight cancer. For example, we are now promoting that eating sweet potatoes can fight cancer, or eating blueberries can fight cancer, or eating purple cabbage can fight cancer.
