The 9th EPMESC was successfully held in Macao in November of 2003. At the end of the conference the Board of the EPMESC series decided that the next conference would be held in a city of the mainland of China. Also I was assigned to be the Chair person of the Conference. No doubt this is a great honor to me and also a challenge because there are so many professional international conferences in computational mechanics happening frequently in the world. After the successful organizing of WCCM6 in Beijing, September of 2004,1 engaged to organize the 10th EPMESC. First of all, I had to choose the venue of the Conference. After some investigation and a lot of negotiation we went to see the site of the venue in Sanya, Hainan Island, the south-most city in China. Finally we made the decision. The most important reason for the choice was the ecological environment of this city. It is beneficial to our health after hard work. We scientists and engineers need a good relaxing place after working hard- a place to enjoy life with friends and family. Sanya is an ideal place and a real green city. Blue sky and white clouds, the peaceful sea and the long beach with white sand, shells and pearls, no pollution and no industry. Everything is so beautiful.
