Its been said that the Chinese have a captive television audience.
After watching a few minutes of all of their available television offerings in a noble attempt to learn their complicated language, a basic fact presented itself.
The Chinese government makes a fortune selling old money and stamps on late night television. They seem to gravitate towards selling money from 1948 & 1965 as they must have stockpiles of currency from those years.
We assume neither the money nor the stamps can actually be used for their intended purpose.
