It can also be written as "〇", which is what you'll usually see in things like years.
Zero in Chinese looks like It looks like an old man meditating with wrinkles on forehead
Can someone explain the orogin of this hanzi? For zero you have rain on top and... what should be the implicit meaning ? :)
Actually, the character "零" IS related to rain.
Originally, "零" means "drops of rain/drizzle" in old Chinese. Later this character was used as the verb "to fall down like rain". You can still see this usage in modern Chinese, albeit not very common and too flowery in conversation:
"凋零": "scatter about"
"涕零": "tears falling down"
Another derived meaning of this character is "tiny bits". as in "零钱" (change, dibs). Which is probably related with the modern usage "zero". However, it's more likely that "零" just had the same pronunciation as "zero" and thus people borrowed this character to write "zero".
Its hard to write this character small while keeping all the strokes.
