Why do postal philatelic companies issue so many stamps, but stamp collectors can’t buy stamps? Especially in county-level cities, it is not seen at all.

This is China Post with “Chinese characteristics”! Postal residents have been calling for N N years! It's still like that! There is no post office, but there are many stamp markets! These stamp dealers colluded with postal personnel, and all the stamps went to the stamp market! Nothing can be done! If you want to buy stamps at affordable prices, just go to the local philatelic department to reserve a few sets in November!
