2014/9/19 Update: It has total 17 speakers announced.
温故知新 comes from Confucius. It means to re-examine what you have learned. The current you and past are different. If you may have new ideas or feeling by re-examing, you are learning new things from and by yourself.
It helps people to accept who they are and where they from, encourage them to face the past and discover new for the future by re-examining on their own.
