Google hasn't been optimizing its Chinese search results for a while now, and a lot of spam sites have taken the advantage of it.
When users search Google in Chinese, there will be numerous spam sites coming out in search results.
Therefore, I made this spam sites blacklist and will update this list as frequently as I can.
You can import this list to "Google Personal Blocklist" or other tools like "Google Hit Hider by Domain" (highly recommended).
