So he was very well-known even though I had not met him. but the first time I met him it was in the late 1970s,when i was the chairman of economic department and he  by basically see it if he could get another copy of his PHD diploma, because it had been lost in the cultural revolution. what i need to do is make a phone call and the university is very happy to replace his diploma and we have been friends ever since. i have met with him in Wuhan at least twice since then. and it is a very wonderful experience and it is also very special previleged to be here with Professor Tan Congtai. we have also known for a long time. i guess we say    ,all is a few years apart after years we were getting closer and closer together. we aged as i aged. it is wonderful experience and wonderful to get back here Huazhong keji daxue and particularly in Wuhan and see so many old friends and to received the award that I was happy just be here. receive the award is very special previlege thank you very very much.

我将在几分种后进行一个“冗长而且枯燥”的演讲。但是在这之前，我想借此机会感谢张培刚基金会，以及所有工作人员，他们举办了这样一个精彩的颁奖典礼。对我来说，这个奖项是一个很高的荣誉，我将好好的珍惜，因为它以张培刚命名。当我还是研究生的时候，我就阅读了张培刚先生的作品，因为他写出了当时最好的博士论文，并且被哈佛出版社出版。虽然我还没有见过他，但是他已经很有名气了。我们的第一次见面是在20世纪70年代，我当时是哈佛经济系的主任，由于他的学位证书在文化大革命中弄丢了，他找我补办。而我当时只是给学校打了一个电话，学校非常乐意为他补办，我们也就是在那时候起成了很好的朋友。从那以后我来过武汉，我们至少见过两次面。

今天我来到这里非常高兴，同时也很荣幸与谭崇台教授一同出席。我和谭教授也认识很长时间了，在一段时间的分离之后，我们的联系越来越紧密，可能因为我们也有相同的年纪吧。

    这是一次非常难忘的经历，很高兴回到华中科技大学，特别是回到武汉见到这么多老朋友，也获得了这样一个奖项。这个奖是一个非常非常高的荣誉，谢谢大家！
