The Chinese government "made up" a name for me for official document purposes. It sounded a little like my Western name and was composed of "good"characters. BTW, that's a danger for both people and companies since Chinese words sounding like the original one might be "bad". Now, in Korea, I just use my Western name, without any problems.

My wife, who is Korean of Chinese ancestry, had her birth name in Chinese characters, so she just used those (with a slightly different pronunciation). In fact, her Korean surname is "Shin", whose Chinese characters are the nickname for Shanghai, where we were living. Our Chinese friends said it was fate.
