Well, I've managed to download the archive. Here's a mirror :

Inside the archive you'll find another archive named "客户端程序未加密-请联系作者.7z" and obviously it's password protected and includes the db + "Client unencrypted" along with the message (from the file name) "please contact the author", which got me thinking that the author intention was to promote and later sell the files. :D
Button line, it took me a day to figure out how to download from baidu, I found out that the files are useless and learned nothing in the process. Hopefully an account on that website will come handy in the future otherwise this was a complete waste of time.
