You say that you cannot read Chinese, but I hope that you have a site with Chinese language content that you are promoting. Getting an English language site into these engines is a waste of time for the most part.
Next, submitting sites to search engines is a dead art. Any worthwhile search engine will spider your site if you have some quality links from sites already in their index. Some even argue that it is preferable to have an SE find you on its own through links rather than using a "submit URL" form.
