Although you don't eat health regularly every season, you should make choices according to your physical fitness and state. For example, you should eat mutton for tonic in winter. But if you have a hot constitution, plus you have eaten a lot recently, or you have a cold, you must not eat mutton. If you want to know when you are suitable for progress, what is suitable for you? You'd better see a Chinese doctor and feel your pulse. Know your physical condition clearly.
