Who is the speaker talking to?

Now that our morning meet-and-greet is coming to an end, please go to the table at the back of the room to pick up your training packet, which includes course materials, articles, and biographies of our instructors. Then find a seat and take a minute to review the write-up of MR. Chen YI, the first speaker, to familiarize yourself with 1-2-3 sales techniques before he comes out to give his seminar.
