Annual Exchange Party is a symbol of the end of a journey. This activity is not only an affirmation to the former community managers, but also an encouragement to the new presidents. The 2019 Annual Exchange Party opened with a buffet reception, providing a platform for free exchange. Then, the speeches of the teacher and the presidents drew a full stop for the past year. It is also a symbol of the beginning of the new journey. The teacher presented the award to the club leaders to recognize the outstanding clubs of the past year. The presidents from the same club wear badges to each other which is a recognition of the work of the old president over the past year and a promise for the new president. Finally, CPO has prepared an Easter egg session named "Call Me, Call My Name" for the Annual Exchange Party to enhance the sense of interaction between the clubs. In the session "Hear the voice of 2019", CPO also prepared a message box for the leaders to write down the feelings about their clubs.
