my 2 cents on 郎平.

If when china really needs her back, and she came back to help chinese team, she is a hero. However, currently, I do not know the chinese team will provide such job offer, y cannot she choose to coach US team? Sports is not war, is to try to let war walking away (i know it is impossible, but this is the final dream of sports). Coaching is the best way for her to make live, just like many of us here in the US choosing different careers; in many cases we work for the US company or even US government, but most of us, at least me, do not felt guilty.

The more chinese coaches get sucessful in other coutries, the more respect we will get. Of course, they will become hero, if Chinese team really need them back. Otherwise, you are wasting their talents.
