Before my presentation, may I invite everyone to join me with a game? Firstly, let's raise our left hand, then stick out one of your right finger, and pat plam of left hand one time. After that, two fingers, two taps, and three fingers, three taps, four fingers, four taps. At last, five fingers, five taps. All right, Thank you so much!
