"Yes," Fan Quan nodded, "that's why when it comes to that, Francis would take a straightforward approach to indicate 'this deck of cards is out of cards, switch to the next one.'"
Ke Yinzhi smiled, "The method he used is to put the two jokers—the big joker and the small joker—together, to remind the person checking the cards 'the information conveyed by this deck ends here'."
"Right," Fan Quan said, "when the remaining quantity of playing cards in a deck box is insufficient to continue representing the letters on the alphabet, that marks the end of Francis's manipulation of that deck." He would then place the "big joker" and the 'small joker' after the last 'card symbolizing a letter' to indicate 'this deck is no longer needed to be checked, you can look at the next deck's information'."
"I see."
