Expanded:
Thirteen games are won or lost by luck, but skill is also important. For example, the two pairs of hands, can be split into two pairs respectively in the "head" and "two degrees", can also be placed together in the "two degrees" into "two pairs". "The decision depends on the situation. Many people have the habit of arranging the order of the cards first before arranging the cards, so that careful opponents can guess whether there is a "flower", "husband" and other combinations.
The smallest combination of thirteen cards may be two pairs without a hwatu. This can be ranked as "粒、粒、滔(two)"(no pair, no pair, two pairs) or "无、啤、啤"(no head, one pair, one pair). In addition to and through the "check-in", the largest combination is: "three stripes, flush, flush", which can get eighteen bets.
