it's stamps of p.r.c. governmental office.
don't do it
counterfeiting government stamp is an serious offence; in most of places in this world, it's criminal activities.
again, don't do it
@john frazer, CL is not an "underground / dark" site. imo, your comments are inappropriate. encouraging others to "recreate a stamp", may i ask, what's the moral?
about "what law in what jurisdiction prohibits that", here're:
provided by @frenzy li. in mainland china, the 中華人民共和國刑法 第二百八十條
in colonial era, there's a "forgery ordinance" in hong kong, which mentioned:
forge or counterfeit the stamp or impression of ariy of the seals
i hope that, this should provide enough info for you, to stop the thinking of "make a stamp that looks like an official stamp".
again, such act is an offence, don't do it.
