Hello. Regarding office PowerPoint, I recommend you to read the book "Learn ppt from Akiba", which was written by Weibo expert Uncle Akiba and his friends. Diversified content, not boring, quick to get started. At the same time, there is a link attached to Netease Cloud Classroom "Autumn Leaves Learn PPT"/course/coursemain.htm? CourseID = 381006 #/courseMain, online courses are different from books. Of course, joining the cloud classroom has more benefits. There are thousands of people waiting for you to learn, make progress and share your growth with you. There are also 35 teachers to answer your questions, as well as free books to learn to take notes, and insist on getting up early every morning to punch in.

Of course, regarding excel, Ji Fang's Excel Application Encyclopedia is the first one. There is also the sister course "Learn PPT from Autumn Leaves"/course/coursemain.htm of Netease Cloud Classroom "Learn Excel from Ji Fang"? course id = 6740 14 #/course main .

I hope it helps you.
