However, looking at health problems from the perspective of social inequality is not easy to resonate and can not achieve the effect of using posters to advocate something (I don't think advocating social equality is a real and effective proposal). People can't really recognize and pay attention to those groups with unequal health environment. So I think people should pay attention to these unequal groups through some social news and real events, so that the public can really do something for them.
