Dear Chris, I have good news to tell you. The World Adolescent Robotics Competition will be held in Tianjin at the end of July. Hearing that you once took part in a Robotics Skills Competition and won an award, I, on behalf of the Robotics Hobby Group, intend to invite you to join our team in the coming competition. I am sure that your involvement will not only help us in winning the award but also enhance the friendship between our two schools.
