For a long time, the “Contents” in our PDF files were not linked to the chapters and headings due to a software issue. When you clicked on a chapter in a table of contents, it would not take you to the chapter.

We have finally fixed this and replaced the PDF files on the server. If you would like to redownload all of them at the same time, get this ZIP file: CheungPDF.zip.

While you are here, if you are interested in the EPUB files to read these materials on your mobile devices, get this ZIP file: CheungEPUB2.zip.
