As the Belarussian answerer said, you give gifts as you would any lady. However, do be aware of some Chinese gift codes:

- Most Chinese value the colours red and gold, because it is the colour of good luck
- Never give any forms of knives as a gift (e.g. letter openers, manicure sets etc) because it is perceived as a symbol of severing the friendship.
- Never give clocks, fake cash (like those rectangular notepads with dollars printed on the back of them) or white flowers–these are mourning items, and receiving them would be perceived as wishing they were dead.

Normally I don’t give personal birthday gifts to a boss, but might initiate to arrange with some colleagues buying a joint gift for her. This makes the boundary clear that our relationship is business, not personal; and it avoids misinterpretation, especially in cross cultural situations.

My top picks for lady gifts are usually stuff she could wear, including earrings/bracelets, handbags, belts, perfume, or a silk shawl. However, these are very personal gifts that could be inappropriate for a boss; especially, if as your username says, you are but a trainee. Don’t forget that Chinese people are very hierarchical, so receiving gifts as such may be awkward for a Chinese woman even if she is very nice.

If you really want this birthday to be your appreciation for her being part of your life, it may be best to get her a gift that she will use up and can share with her someone special. This may include vouchers to dine at her favourite restaurant, get pampered at a fabulous spa, stay at a hotel in a nearby weekend getaway spot, or enjoy an evening at the opera if she’s into that thing. If you don’t want to spend too much, vouchers for Starbucks or a movie would suffice. But whatever you get her, make sure you have two of them included, because (especially if you’re a man) it’s not as nice to receive one of these and not be able to take her someone special with. Not only is including two a sign of respect for the possibility that she may want to spend it with someone special other than you, but also two is a lucky number in Chinese numerology.

If you decide not to have a go at any of these, a birthday cake jointly bought with your colleagues to be eaten in the office/wherever you work never fails. Don’t forget candles! Party hats & horns and decorations would be nice, but optional.

If someone give me a gift, they don’t give me a Belarussian gift. They give me a Japanese gift. Or they give me a gift that is not of a particular country (just a "normal" gift).

So, give her a type gift that you give to someone else who is not Chinese.
