Fiona Fang talks about health.

Physical exercise promotes blood circulation. Blood circulation can transport a lot of oxygen and nutrients and take away a lot of metabolic waste. Sufficient oxygen will make your brain clear, concentrate and work efficiently. As said upstairs, you often hang a drip because metabolic waste can't be excreted in time, and your immunity is low and you are prone to get sick. Dizziness is naturally caused by brain hypoxia, long-term study and work, and lack of rest. Therefore, health is the capital of the revolution, and a healthy body is the basic guarantee for you to learn well. You can run after class or exercise at night.
