Mr. Wu is playing poker with his business friends. Mr. Wu has 13 cards, including spades, hearts, diamonds and clubs, all of which have at least four patterns.

So there can't be two societies, but there should be more than two;

(2) If spades =2 and hearts =4.

Square =3, so,

Plum blossom = 13-2-4-3=4

Do not meet;

(3) If the diamonds are 2, the spades are 3.

So hearts =3,

Do not meet;

(4) If the hearts are equal to 2, the hearts of spades are equal to 4.

Square =3 1, so,

Plum blossom = 13-2-4- 1=6

Only this is suitable.
