Well, I had a translation course yesterday. My teacher told me that I made a mistake. There was a Chinese writer, named "Bing Xin". I didn't want to translate the writer's name into "Bing Xin", because if I tranlated it into this, do you really know what did it mean? "Bing Xin" can be translated into "Crystal Heart", or "Ice Heart" according to its meaning. I did so, and argued that people may make mistake in pronouncing "Xin". So here I want to ask how you will pronouce this word. Like"Shin" or "Axin". Thank you in advance!
