Or let's say this: The term of an institute director is three years. If after three years they want to continue as institute directors, then it would be reasonable to ask them to give up their dual nationality. We should give them a chance to decide whether or not they can truly flourish in this environment.
或者，我們所長的任期是三年，三年之後他還繼續當所長，再請他放棄是比較合理的，也讓他們考慮能不能在這個環境裡真正發揮。
