Medicine
The ailment that often occurs during a travel trip is to catch a cold, especially in regions that are in unsettled weather. Ensuring you have a happy tour, some flu medicine should always be in your hands.

During heat wave, bring adequate drinking water with you on the road. If the illness occurs, the patient should leave the high temperature area, take off clothes, drink some water with small amount of salt added or take "Ren Dan" and "Huo Xiang Zheng Qi". If the problem persists still, the patient must be sent to the hospital.
