Some interesting comics

This week's reading once again discusses the price of traditional textbooks and the benefits that OER textbooks can bring to students in terms of cost and learning. The high price of traditional textbooks seems to be a problem that students urgently need to change. It is not hard to see the pressure and frustration of expensive textbooks on students. Sadly, this may continue for a few more years. When I was studying art, one of my courses included comics. One thing about comics is that comics can express some cruel problems in reality in the form of humor and exaggeration. Here, I found a few interesting comics online, and I wanted to share them here. Hopefully, when we look at these comics and smile, we can also think about the fact that if OER can be realized, the bitterness in these comics will disappear.
