Can someone identify these marks on the bottom of a blue porcelain bowl? (Characters identified: 中王國 賈泊氏) Can someone please identify these marks on the bottom of a bowl?  

賈中
伯王
氏國
It's probably 中王国 贾泊氏.  

And I did some search and found that this picture should come from some antique forums. However there's no canonical record for it. This piece of porcelain is probably modern made. On this site, a person said:


  It's "fake scholars will finally subjugate the nation".


(read left to right instead of right to left)

(假博士终亡国, which has the same pronunciation as the original words)
