Our hotel lobby has gotten this striking Lunar New Year tree with the little hong bao envelopes. These are handed out at family and social gatherings such as those for the Lunar New Year (the ones on the tree are just for decoration and as symbols of prosperity). Some pointers : the amount of money in an envelope should end in an even digit but not a 4, and it is best to put a single crisp note in (so that the envelope is not bulky). I bought the little envelope with the happy guy on just for fun – there are many many different designs available but the color is always red. The classic red lantern is from the entrance lobby of our offices at work.
