I came back from the United States last year, and I had stayed in Stanford for six years before that. I want to introduce a lot of new things. Recently, Beijing's census is completed. We are ranked first in two aspects: one is the prevalence of hypertension; the other is the prevalence of hyperlipidemia, which is regrettable. The Municipal Committee takes it very seriously, and has issued documents requiring all units to learn more about the latest health care knowledge. That's why I'm here for.
