I am not familiar with this piece and, unfortunately, the Chinese characters are too worn to read.
The character at the upper right looks like jia (åŠ ). Besides its basic meaning, jia is sometimes used to transliterate proper names.
The character at the lower right looks like zao (e€ ).
The two characters beneath the swastika are too obliterated to read.
I'm not sure what the two characters on the left are.
The character on the reverse side is tian (天).
I purposely have not provided translations of these characters because their meaning could be different depending on the context and, with so little information, I have no idea what the context may be.
As Sap mentioned, the swastika is an ancient symbol of "good luck". However, it can also used in the place of the Chinese character wan (万) which means "10,000" but has the extended meaning of "myriad".
Also, it is unclear why there is a "dot" (star? sun?) in the lower left.
This piece is not necessarily Chinese. It could be from Japan, Korea, etc. in which case the characters are sometimes written differently.
I'm sorry I cannot be of more help.
Hopefully, another forum member can identify the piece.
