A、In Thailand. B、In Europe. C、In Bulgaria. D、In India. DIn which country is it impolite for people to use the left hand for pass

Learning the language of a country isn’t enough. If you want to find out about the manners of your foreign friends, you will probably be surprised just how different they can be from your own.
    A visitor to India must remember that it is not polite for people to use the left hand for passing food at table. The left hand is for washing yourself. Also in India, you might see a man obviously shaking his head at another to show that he is disagreeing. But in many parts of India a rotating movement of the head is to show agreement. In Bulgaria you shake your head to show "yes" and nod your head to show "no".
    In Europe it is quite usual to cross your legs while sitting and talking to someone, even at an important meeting. But doing this will cause anger in Thailand. Also touching the head of an elderly person in Thailand is very impolite.
    Knowing about manners is useful when you are traveling, but you also need to know the language used to express the manners.
