Today we get together to have a send-off meeting. We feel greatly honored to have a chance to work with Mr. Blue for two years.
As we all know Mr. Mark Blue came to China from Germany in the year B00D, as an expert in architecture. In these two years, he has devoted all his energy to the design of our Olympic village and helped us a lot. We thank him for this magnificent work, through which we have established good relationship to each other.
Mr. Blue is going to go back to Germany the day after tomorrow. We wish to take the opportunity to convey our best regards to his family. He is always welcome to come back to China again. And we hope him a very pleasant journey on his way back.
Thank you !
