It would appear that you are no longer an admin of the wordpress installation. Did you by chance add it to your ww.wp.xz.cn sites if so you would be able to change it there I think. You may have to do it via PHPmyadmin.
Are you by chance using a image plugin of some sort? Is so you may need to check the settings in that. Its calling for the image to stay the same size even when the page is smaller like mobile.
This is what worked for me
Under
.sociable ul li {
background: none;
display: inline !important;
list-style-type: none;
margin: -5px;
padding: 0px;
Hope this helps someone.
