- Are 乒 and 乓 used in classical chinese? 2 answers
倪阔乐 pointed in his answer, 乒 and 乓 have onomatopoeic use and these characters were "chosen for the sound playing the game makes" and it's a Great explanation but....
When I see 乒乓 together I see the picture of "table" with their legs (丿丶) plus a "net" on it. Not you ?
They looks like pictographic characters but using not one but two characters instead!
Primarily I was asking the etymology and if they have they other uses ? (this part is filled, thanks!)
