There are also many many people with the surname "Wong." As legend would have it, Cho En-Lai devised a methodology in the 1970's which seem simple enough and effective. By central degree, every Wong was listed and given a number. So, for example, a particular Mr. or Mrs. Wong would be Wong No. 7294117. This seemed ingenious and solved the problem, until people started answering the phone. Apparently, what would happen is this: A Wong would pick up the phone and start to answer "Wong Number..." and before Mr. Wong could finish stating his number... the caller would HANG UP!!!
