Main Etiquette of China
Etiquette of Gift Presenting: There are mainly the following several situations of presenting a gift festival, wedding, birthday, gratitude, help, sending-off relatives and friends, and returning the gift. The most important thing of presenting a gift is to show intention. As the saying goes, a goose feather sent from thousands of miles away is a present little in size but rich in meaning. One should choose and purchase a gift according to his own economic conditions. In this way, the gift receiver will accept the gift with ease of mind if he knows the real situation he is in. Attention should be paid to this point. When presenting a gift, one had better wrap it with exquisite wrapping papers, which not only show there have been much anxious thought entered into the gift, but also raises the curiosity of the gift receiver.
Etiquette of Visiting a Sick: The Hospital is a special site for healing the wounded and rescuing the dying. Therefore, before going to a hospital, one should have a clear understanding of the ward the sick person is in and the sick bed number in case he might make inquiry at all places and hence disturb the composure of the hospital. Before visiting a sick, it is best to prepare a gift.

Wedding Etiquette: Nothing is happier than two lovers getting married in life. Getting married is one of the great joyous events in life. As a friend who takes part in the wedding reception, you should choose and purchase a gift in advance. It is best that the gift has some meanings. For example, sending ninety nine roses stands for 'everlasting', or sending a golden congratulation card of memorial value and a wedding cake to express your gratitude and good wishes.
Birthday Congratulation Etiquette: Birthday congratulation is actually congratulating on one\'s birthday. When congratulating on an elder\'s birthday, you have to pay more attention to etiquette as there will be slightly more etiquette. When congratulating a friend of the same generation on his birthday, you don\'t have to comply with formality and present a gift. In case of congratulation on an elder\'s birthday, apart from being particular about clothing, you must bring a gift which contains the meaning of health and longevity, such as an exquisitely designed cake or a memorial gold congratulation card.
Funeral and Interment Etiquette:The traditional funeral has heavy and complicated rites and trivial procedures. Now a memorial service is generally held to show condolences for the dead. Attention should be paid to some etiquette when taking part in a memorial service. In order to honor the memory of the dead and show concern and sympathy for his family members, you should present a wreath or face cards.

Tips: Taboos on presenting a gift in China
There is a prevalent saying in China that happy events come together. Hence, whenever an event of great rejoicing and congratulation occur, the gifts will be all sent in even numbers and accordingly those sent in odd numbers should be avoided as taboo. However, Cantonese avoid the even number 'four' as taboo, for 'four' sounds like 'death' in Cantonese, which is not propitious. You can see another example here. Though white has the meaning of purity and flawlessness, the Chinese people tend to abstain from it, because in China, white is often regarded as the color of great sorrow and poverty. Similarly, black is considered as unpropitious. It is the color of calamity and grief and mourning. However, red as the symbol of happy event, serenity and festivity is regarded with great affection by the general public. Moreover, Chinese people often avoid sending bells to elderly people and pears to a couple or lovers, as in Chinese language, 'sending bells' have the same pronunciation as 'attending upon a dying relative or burying a parent' and 'pear' sounds the same as 'leave', which is not auspicious. They are neither allowed to send medicines to healthy people and undergarments to friends of the opposite gender.
