Hello everyone, my name is Yixing Chen. I am a fourth-year Econ student, the reason that I chose this course is I take this course as an elective. And It is an online course, so it will not take any time spot of my schedule. This summer will be my last semester at Uvic. I am very happy to study with all of you. Right now, I am studying outside of Canada, and I wish everyone to stay safe.
