Traveling to another country is exciting and fun.But if you don't learn about local traditions，your trip may get into trouble.To help stop things like that，I list some cultural taboos （禁忌） in several countries.Let's take a look and then you can have a great trip there.
    Mexico
    In Mexico，bringing an expensive gift to someone's home is a no-no.It could be seen as a bribe （賄賂）.For local people，some simple things like flowers are good gifts.But you shouldn't take along red flowers，because in Mexican culture，they symbolize death and can be connected with witchcraft （巫術(shù)）.
    The US
    Americans have a tradition of tipping （給小費(fèi)）.You can tip waiters，taxi drivers，hotel doormen…nearly anyone with a service job.
    Pay attention when you talk with Americans.Questions like "How old are you？" may be common between friends.But as tourists in the US，it is not polite to ask people's age.
    Britain
    British people are known for queuing （排隊(duì)）.From the supermarket to the underground，queues are very common in Britain.Usually，it takes a British person six months of their life in queues.If you jump the queue in Britain，you may make them angry.
    Japan
    You should never wear shoes indoors in Japan.When visiting someone's home，it is rude to enter with shoes on.Shoes should be taken off at the door and replaced with indoor slippers （拖鞋）.This is also the same when you try clothes on in a clothes shop.You should take off your shoes before going into the fitting room （試衣間）.There are indoor shoes prepared for customers inside.
