What is the character with the greatest number of strokes?
1) 'biang'

Well, the first one that came to my mind is 'biang', as in 'biang biang mian' - which a quick Wikipedia search shows has 58 strokes. This is still in some use (and I've seen it in restaurants), if that means anything to you. It is not, however, found in dictionaries.



2) 'zhe'

Sadly however, biang doesn't have the most strokes (although I would argue it's the most complex) - Wikipedia has a page on complex characters as well, and according to them 'zhe' meaning verbosity was the most complex/has the most stroke orders - possibly the character you are referring to, as it is just 'long' times four:



3) 'zheng'

It also mentions 'zheng', another 64 stroke character meaning flourish, as being equally as complex:



The page on Wikipedia goes in to a lot more detail, so I suggest you check it out.

Hope this helps!
