Similar in design to China issues from the early 1920's, though I'd note that the genuine stamps from the era say "Republic of China" or "Republic of China Postage," not "Chinese Republic Post." I don't recognize the center designs, either.
Maybe a trial, maybe a fake, maybe just something I can't find.
The design details/quality of the OP's stamps do not match the so-called 'essay's". I call fantasy items printed for packets and the collector's market.
