According to the speaker, why is the event being held?

Welcome to the Brewster Beverages Sportsfest. As you all know, we hold this event to promote team spirit among our employees. By playing various games, we also aim to develop a competitive spirit and the determination to succeed. Over the next two days, each department will compete in several games, with the winning group receiving a special package trip from Legend Travel. Before we start the first day’s activity, I’d like to thank the Green Ridge Complex for allowing us to hold our event here. We hope everyone has a wonderful time. Now let the Brewster Beverages Sportsfest begin!
