Dear President Sun and Dr. Li Jiamin,
I would like to express my sincere gratitude for all the hospitality that you and your team extended to us at PTCOG. You had a flawless organization, the meeting places were very well organized, it was very interesting to visit your Proton Center and the intellectual level of the PTCOG meeting was excellent.
There is simply nothing that I think you should be doing differently in the future �this meeting was just about as perfect as one could organize it.
I personally greatly enjoyed the visit and the opportunity to experience your country �although I wished I could have stayed longer.
I also would like to express my deepest gratitude for the Professorship at Wanjie Medical School . This is a great honor for me.
If there is anything that I can do in the future to be of help to your program �either by teaching or by consulting on patients �I will gladly do so. Also, should you wish to come to Switzerland and the Paul Scherrer Institute, I herewith would like to extend an invitation to you.
With best personal regards and many thanks
Eugen Hug

对你们和你们的团队在国际粒子（质子）肿瘤放射治疗会议中为我们所做的一切和热情的款待表示衷心的感谢。你们是完美的组织者，会议被安排得相当好。也非常高兴能够参观你们的质子中心。这次会议的学术水平也很出色。
我想今后都没有什么地方可以做得更好了，这次会议近乎完美。
我个人非常高兴能够有这样的机会到中国，虽然这次本来还希望能够再多呆一段时间的。
我还想表达对于受聘为万杰医专教授的诚挚感谢，这对我来说是非常荣幸的。
如果今后需要我提供任何的帮助，无论是教学或者是患者的咨询，我都非常高兴，当然，也非常希望你们有时间到瑞士来。
再次表示衷心的感谢和祝福。
