What characters are on this ceramic jar? What characters are depicted on this old jar? My (art-)sources have all different opinions: "fu2 shou4 an1 kang1" or "fu2 lu4 shou4 xi3" or 4 x shou4 or "fu2 shou4 kang1 ning2" and all without telling which tree is what character.
It should be 福壽康寧 (fú shòu kāng níng; simplified: 福寿康宁).


福
康
壽
寧


I'm pretty certain about the first 3; 寧 is the only one that is hard to tell, but based on context, it should be 寧.

EDIT: And this is what it means: good fortune, long life, health and peace
