* committed a file into the wrong directory on June 9

This is a stupid mistake, I found that there missed one chinese version file that I committed yesterday, finally I realized that it was in the wrong directory. The fact that it isn't in the right place can cause a real problem, because all pictures can not be shown. So please merge this modification.
