In 2003, ISPA 26th Annual Colloquium would be held in China. Together with my colleagues, during about one year time, I plunged all my spare time into the preparation for that colloquium. Everything went well before the spring of 2003. As everybody knows, it was unfortunate that the worst thing happed, SARS came. We insisted on working with our best wishes. But at that time, the human being could not stop it. With the greatest sorrow, we, together with EC of ISPA, had to cancel the colloquium at the end of April, although we did have got more than 100 registrations at that moment. We sent back every penny to everybody who had prepaid.

　　In the last Colloquium in Athens, we once again got the new glorious project from EC to hold the 28th annual colloquium in China.

　　In the past 12 months, all of us kept working hard during our spare time. In many nights I could not fall asleep even the whole night, planning what should be done in the following days, considering what should be sent out and what should be taken in. In some days, especially during May and June, each day I could get more than 20 to 30 emails and post letters, and also, more than 20 to 30 emails and post letters should be answered each day.

　　Now, what happened to us is only the past, and what we expected has been realized.

　　I would like to say, only if all of you feel happy, get excited, sense successful while your staying in Hangzhou during the past 5 days, my dream has really come true.

　　Thanks! Thank you a lot for your enjoyment and your appreciation!
