Dear all,
Sorry, but the article is out of update. According to http://www.baidu.com/search/baike_help.html#%E7%99%BE%E7%A7%91%E5%8D%8F%E8%A... , Baidu Baike has changed to use the Creative Commons BY-NC-ND. Also, it said:
* Use of non-commercial use should give the author name and Baidu Baike * Use of commercial use should ask for author's permission, and state the author name also Baidu Baike * Use outside Baidu Baike must be the same meaning of the author, and also ask for Baidu's permissions
So, I don't think that Baidu Baike will change their copyright notice and Wikipedia will continue to mark them as copyvio. Due to this issues, the copyright related page of Wikipedia is updating. However, the problem is they copy the content from Wikipedia and ever from English and Japanese Wikipedia. Search WP:BD and WP:BAIDU on Chinese Wikipedia for more details.
