It's surprisingly heavy to listen to Hangang's Hangang; I don't think this is a lecture that you can understand after listening to it once. However, it seems like a good lecture to learn deeply while working as a practitioner. If I have a wish, it's that the current Django version is version 4, and at the time of the lecture, it was version 3. If there are any parts that have improved or parts that are not compatible, please improve them (there haven't been any yet)
