Autumn is a flourishing period of allergic reaction to pollen. The allergic person must pay more attention when going out, and if necessary, you should wear a breathing mask or a scarf and do not close to the flowers that could cause allergy. It would be well not to pick the unknown wild flowers or take them home at will or stick them in hair. Do not travel when it’s windy, because wind can speed up the dispersing of pollen.
In autumn, the poisonous insect, snake and hornet often conceal themselves in the dense bosk. When meet them unexpectedly, people may be attacked. There are many ways to fight them, and more practical one is to find a stick with about one meter length, used to drive or kill off them. If you are not confident to do that, do not yell when meeting them. In the event of being attacked, try to express the poison liquid from the wound and go to the hospital for medical treatment in time.
In autumn, you’d better travel in a group, and try not to be alone. Although it is a good chance to ease up, but safety is more important. Do not forget to take a tourist map with you in case of an emergency.
