usually I tell other my english name, but when fill out some official doc, i use my chinese name like passport one, and u can add like ' (Jack) ' following ur chinese name if you want. I used this way for 8 months, no problem at all.
Urgent: How can I start to use my English name officially? Does it affect my previous documents of Chinese name? Who can tell me a win-win solution to both Chinese and English names?
