Baidu is the biggest search engine in china and the second biggest in the world. The main problem is that is uses the chinese character set which makes it difficult for english reading or speaking users to know which page is used to submit url website link to the baidu search engine.
here is the link to submit your website to Baidu.com search engine.
www.baidu.com/search/url_submit.html
All you need to do is to place your URL, type the passcode (letters you see displayed) then hit the button on screen.
It is not known how long it takes for Baidu search engine to crawl your website link and acually index your website, but its worth the try.
