Bing-bang or ping-pang

As a matter of correct pronunciation, the chinese words for table tennis 乒乓 is pronounced "ping-pang" and not "bing-bang".

Not many chinese are sensitive towards correct pronunciation especially the use of 翘舌 eg "zh" instead of "z" or between "ch" and "c".

I hear a DJ pronouncing 结束 as jie-su when it should be jie-shu.
