Dear friends:

Many people have got a headache, cold, or felt tired. In order to help students to prevent colds I provide the following tips for their guide:
1) Wash face by cold water, immerse feet in warm water and gargle with diluted salt water.
2) Open windows to get fresh air.
3) Dry bedding in the sun.
4) Do exercises everyday.
5) Go to public activities as few as possible when influenza is rampant.
Prevention is better than cure! 希望你能满意！
