Aha, I understand now. I am sorry you are having such trouble! It seems that 3.5.51 does not import the .skel file correctly, even though the 3.5.51 Skeleton Viewer shows it correctly. Unfortunately 3.5.51 is very old and it is difficult for us to work on. 🙁
Are you able to tell what the problem is? Maybe you can fix it by increasing the scale on the region attachments F_tou, F_zhengyan, and F_xiong?
Ideally you can find the .spine file. Have you looked in the Spine backup folder on a computer that was used to create the project? To find that folder, in Spine go to Settings, Files, Backups, and click Open.
Actually, I managed to verify that 3.5.51 does load the .skel file correctly, however the images extracted from your texture atlas are too small. Spine uses the actual image sizes while Skeleton Viewer uses the sizes stored in the data. This means Skeleton Viewer scales up the images so it looks right (but pixelated) while Spine shows the images using their actual size, so the images are too small and the skeleton looks wrong.
It looks like your atlas was exported with a scale of 0.5. Here I scaled up the face and eyes images to be twice as large, and it looks about right:

Instead of scaling up your images, all you need to do is import the binary data using a scale of 0.5. I have done that for you and here is a 3.8 project file that looks right in Spine:
