@regardthefrost @DrEricDing Adjusting directly from the demographic pyramid would only make sense if infection and disease severity were uniform and all ages had equal risks apart from age, but that's not the case.
@regardthefrost @DrEricDing 仅当感染和疾病严重程度一致并且所有年龄段除年龄外具有相同风险时，直接从人口金字塔进行调整才有意义，但事实并非如此。
