I know a lot of Chinese characters are either a symbol of something or a combination of symbols in the space of one character, so what's the origin of the symbol for numbers 4, 5, 6, 7, 8, 9? since knowing what the symbol is suppose to represent does make it much easier to remember, eg. the symbol for tree is a simplified tree branches with roots.
I need to explain a fairly large group of people how to count from 1 to 9 in chinese, in at most 3min.
I personally memorized them fairly easily, but don't think most people have any chance in 3min to just pick them up on the spot, so is there a pattern to them (for 4 and above) that can be used to help people pick them up quickly?
I've considered teaching the Chinese 1-9 single-hand gestures as a "teaching tool" but don't know what the pattern/correlation between those is either.
To avoid confusion I'm referring to the traditional chinese numerals (modern ones are very much the same as far as I know). Not the so called "capital notation" used in checks and official documents, and not the so called "mercantile notation."
