Ugh, I didn’t look carefully. When I uploaded the PDF, its file size was 17.9 MPa, which is way too large. Since I had previously compressed PDF documents and found that their size hardly changed, I thought I would divide it into two documents of roughly equal size this time. But I didn’t expect the file size to decrease so much after compression. Thanks to the moderator for the reminder; I’m uploading it again. Those who need it can download the version below – saving a little money is always good, haha.
Thank you to the original poster for sharing; I needed it just now
