1. Pay attention to personal safety and keep in touch with family and friends at any time. If you take a long-distance taxi, you'd better send the license plate number to your friends.
2, you need to pay attention to food safety, don't eat roadside stalls on the street, be sure to go to a regular restaurant to eat.
3, don't "big bags" at first, take daily necessities and change clothes.
Don't talk to strangers, and don't eat strangers' food at will. Be careful outside to avoid unnecessary accidents.
