　　Dear Sirs

　　May we have a copy of your brochures concerning the meeting, which was held on July 10, 2006, for announcing projects on industrial development in the Northwest China.

　　Yesterday's China Daily included an article about the meeting. Some thoughts and plans were presented on the electronic and water-treatment fields. We would appreciate more details than those printed in the paper.

　　It would be most helpful if you could send us all the necessary information. We are sure it will be benefited to both of us in the near future.

　　Yours faithfully

　　Bruce Lee
