Could you tell me some customs in giving presents in China or in other different countries?

The following is a general list of the rules and customs that are followed when giving gifts in China.
1: Offer gifts that are best used by everyone in a family, if that happens to be the group you are presenting the gift to. Simple and inexpensive gifts are the best, as highly expensive gifts may be awkward and refused. Things like pen sets, a small product of food (grains, rice, etc), or similar, non-personal items are fine.
2: Wrap the gift in wrapping paper. Take your time and do a neat job of it. Don't leave the gift in a shopping bag. The gift should be wrapped in a color that is appropriate for the occasion. For example, a normal, happy occasion would require 'red' paper, a funeral would require black and white, and a wedding is best with gold and silver.
3: Expect the gift to be refused two or three times before accepted. This is customary, as it shows that the receiver is not being greedy. You, the giver, should offer it again after each refusal u
