Significant Chinese Numbers?

[abracanabra]

What numbers (and especially time periods) are significant in Chinese myths/fairytales? For example, in Western culture, the numbers are 3 and 7--three brothers, three years of a quest, seven years penance, etc.

Eight is lucky because either the written character for 8 looks like the character for luck, or the spoken word for 8 rhymes with the word for luck. I forget which. When you eat moon cakes for the harvest festival you're supposed to cut them in 8 pieces, for good luck. All told to me by a Chinese co-worker who brought me some fancy moon cakes, which were not very much like western-style cake.
