You should be careful in the giving of gifts. Never give a gift in a job
interview or go to a business meeting. Gifts are usually given during special
holidays or as "thank you" for special invitations.
       At the time of arriving, you may give your gift to the host (主人) once
the introductions are made. With gift giving a few rules are in order: Be
modest  (适度的 ) with  your  gift, do  not  buy  expensive gifts.
      Special food from your country or a bottle of wine are best if you do
not know the host very well,but be certain that your gift will not require
attention. You can usually say something like "I thought you would like
this a little later" when you offer your gift.
     Be careful of giving wine , a bottle of wine is usually all right if you
know your host drinks wine. Flowers are good but remember: roses are
for personal relationships. Do not give roses. Cut flowers are nice if they
are in a vase(花瓶) . A small cultural gift from your'country is usually
very suitable. 
     Make sure your gift is packaged nicely with a nice card.
