Help with identifying a makers mark

[sotexreb65]

I am hoping to get some help with a maker's mark on a china set i recently purchased. It is at least 20 years old and i am not sure if it is older than that. i have included a picture of the mark and the pattern if anyone can help please let me know.

Thank you,
Aaron

The Chinese says Zhongguo Tangshan. The latter is a place name, but could also be a porcelain manufacturer's name. Items with this mark cannot be very old.

i wasn't really expecting 100 years old but i am pretty certain at least 20 years old. thanks for your reply.
