Antique Bowl with etched Ancient Chinese Art

by shannon
(Ca, USA)

Looks very old and valuable. Would like to know if anyone knows if the art is BC or AD.

The Bottom of the bowl is engraved CHINA and another 4 letter word with letters that appears to be K Y N and maybe another c hard for me to read.

The year of the artwork alone is what I am the most interested in.

Any info you may have would be greatly appreciated.

Sincerely;

Shannon
