Who knows what are the four words on each RMB stamp?

The seal on the back of the new version of RMB is "Seal of the President", which is: Line-upper right; ? Long- lower right; ? One-upper left; ? Chapter-lower left corner.

The seal on the RMB is a symbol of the power of the national banknote issuing agency, and it is also an internationally accepted banknote issuing factor. The president's signature is printed on the banknotes of many countries in the world. For example, the euro, whose currency name is written in Latin and Greek, and the abbreviation of the European Central Bank and the signature of the governor of the central bank are displayed on the banknotes in the five official languages used in the European Union (such as BEC, European Central Bank, EZB, EKT and EKP).
