International travelers, whether traveling for business or pleasure, will find themselves solo from time to time. Here are a few ways to meet new people and perhaps even get new travel chances.
Make yourself friendly
Be relaxed and polite. Remember to put yourself in social activities. Restaurants, shops and parks are all great places to meet people. If you want to make local friends in a country, stay near the place the locals often visit.
Show your photo album（影集）
Keep a small photo album in your bag when you travel. Photos of family, friends and pets will help your new friends learn more about you and give you things to talk about. They will share their own stories with you, and it will help you learn more about your new friends.
Share something special
Can you help your new friends improve their Chinese? Can you cook a traditional Chinese meal? By sharing your skills, you can have a close friendship with your new friends that they won't soon forget.
Give some gifts
Many foreigners love Chinese goods but have to pay a lot when buying them in their homeland, so you'd better prepare some gifts such as silks, tea and works of art. They are always popular.
Exchange flats
If you and your new friends get along well, you can give them your information and plan to exchange flats for your next trip. Then you can visit their countries and stay in their houses while they stay in yours. In this way you will improve your friendship and live like a local abroad, but pay less for traveling.
