Today I help my sweetheart to take the lesson in university which is talking about the digital economics.

The female lecturer was quite green and lack sufficient teaching skill. For example, she disordered the PPT slides which make some of classmates annoyed.

After that, I went to my university to borrow books for my sister. I have promised to do so several times but always did not take action. Consequently, I decided to make it even though it quite costed time.
