:Hi Yuan, I was dropping by to talk about this, too. One important Wikipedia policy to keep in mind is that all information must be cited to a reliable source. This is particularly important in controversial cases. It appears to me in edits like this one  that you are not providing a source. Can you give a reliable source for this per the policy at WP:RS? If not, unfortunately, it will have to be removed. 
 :If you are worried about your English, another option would be to leave a note at the talk page about the information you wish to include, and other editors (me included) will be happy to discuss and see if it would be a good addition to the article. Cheers,
