If you search for "China" in Yahoo, you will get such a list of addresses in the browser's address bar: http://search.cn.yahoo.com/search?ei=gbk&fr=fp-tab-web-ycn&meta= vl%
3dlang_zh-cn%26vl%3dlang_zh-tw&pid=ysearch&source=ysearch_www_hp_button
&p=%d6%d0%b9%fa&submit=
Looks a little messy, simplify: Http://search.cn.yahoo.com/search?&p=%D6%D0%B9%FA
That's the key. Where &P=%D6%D0%B9%FA is the keyword parameter of the search, and%d6%d0%b9%fa is the "China"
URL encoding. OK, all we need to do is construct this code.
