On 20 August 2020, It was a great honor to join the IMUSE 2020 Session hosted by Tsinghua University. Through lectures and group discussion, I learned a lot from students from universities in the US. Also, a discussion and exchange of experiences in online learning showed similarities and shared concerns of the effectiveness and sustainability of this approach. It reminds us to reconsider and reconstruct a sustainable and resilient teaching and learning for the post-COVID 19 world.
