Didn't the eclipse say that you suffered in the west first? Why is the picture in the book the existing gap in the East?

Your understanding is absolutely correct.

The eclipse is the first loss in the west, and the photos of the eclipse should also be viewed according to the orientation of the constellation: up north, down south, left west and right east.

When you look at the map, look down, the north is on it, and the east is on the right.

Look up when you look at the star map, the north is on it and the west is on the right!

You'll understand if you try.

The picture below shows the whole process of the solar eclipse I filmed in Shenyang on July 22 last year. Only one partial solar eclipse was seen in the total solar eclipse in Shenyang.

The lower left corner of the picture is "First Lost" and the upper right corner is "Last Contact".

If the gap in the photo of the eclipse you see is on the right, it is the beginning of the eclipse.
