Suits and ties are worn all year round, even in summer. Do not dress casually unless asked to do so. Gift-giving to business associates is not expected. A Chinese recipient will open the gift privately later, since it is considered inappropriate to open it in front of the giver, or to be too effusive in one's thanks. And giving sharp objects such as knives, could symbolize the cutting off of a friendship.
Flowers are appropriate at grand openings and as gifts to businesswomen.
Business entertaining is central to Hong Kong life. Chinese banquets are shared from large dishes in the centre of the circular table. The host will order these, and serve the guests. Everyone is expected to use chopsticks, but of course forks and knives are available on request. As a formal dinner has 12 courses, it is wise to eat only a little of each.
