Why are the Q.K.A.2.Joker in playing cards in this order? Why is A bigger than K and 2 bigger than A?

The earliest order of poker was A( 1), 2, 3 ... So, in the 65438+5th century, the French changed the rules and made a symbolic comparison with K (each K represents a king). This rule began to spread abroad after the French Revolution. Later, the Germans further made 2 bigger than A. Central and Eastern Europe are greatly influenced by German rules.
