Ok,I've tried my best,Chinese(and Japanese make my eyes go
) so I think it says,top right to left 'Jiangxi',a province,then bottom right to left,'Jingdezhen' make or made is the last character which,I think is used in reference to companies produce,the date from the mid 1960's onwards,it's very confusing the kanji dictionary I have(Japanese) has 47,000 character variations so confusion is an understatement
