Uncle,
Even so, your book will be the same as the English version.
X technique is this: Open the book. In your mind see an imaginary X connecting all 4 corners of the pages. Top left corner down to the lower right corner. Top right corner down to the lower left corner. This makes an X.
Relax your eyes. Do the tangerine technique.
Then open the book and see an imaginary X connecting all 4 corners. Start turning the pages relaxing your eyes and at the same time seeing all 4 corners of the pages. Once you can do this, you don't need to see the X.
good luck
