Pai Jiu was a card made of hard materials such as wood, and there were 32 cards in a deck of cards, which was a bit like "fighting big" in poker now. "Tianjiu" is a name for Pai Jiu when it is published, which is similar to "King Kong" in "Fighting Big", but there is also the greatest "Supreme" in Pai Jiu. Of course, if you hold a pair of "Tianjiu" in your hand, it will naturally be a good card.
