thank you.but I can't to see your picture. I'm  Chinese

Sorry I do not know how to post a picture directly here.

Try the light coloured brick above the knight    to the left of shield    at the bottom right of the picture 

Go to imgur, right click on image, chose copy image.  Then come back here and paste.

If this is what you just did, right clicking on your image still shows the imgur site, so I doubt it would be visible in CHina even on that forum.

Right clicking on images from the poster we can see it's from "https://s1.plumeta.com/" but that doesn't seem easy for us to upload there.
