There are many unusual customs around the world. If you travel there, it's important for you to know about them.
Greece
If children are changing their teeth, instead of saving their teeth and placing them under a pillow (枕头) for the tooth fairy (仙子) to collect, Greek children's teeth are thrown to the roof of their homes. This unusual tradition is thought to bring good luck for the family, as well as a healthy tooth for the child!
China
When dining with locals and traveling in cities, it's important to give out gifts as a way of saying thank you. But remember to avoid giving them the following gifts: clocks, handkerchiefs (手帕) , shoes and anything white or black. It may seem like a good way of saying thank you for their lovely treat, but they are each strongly connected with death and funerals. A proper gift to pass on to show your thanks is delicious sweets or fresh tea.
Thailand
This is probably one of the most unusual customs to look out for, but it's also a lot of fun—especially for your kids! Every November, in the town of Lop Buri, the locals lay out fresh fruit, cakes and candies on top of tables that line the streets. But these mouth—watering treats aren't for the people, they're for the native Macaque monkeys to enjoy. This strange but wonderful celebration is called the Monkey Buffet Festival, and is a must—see on a trip to Thailand.
