The steps are as follows:

1. Hand shuffling method. Hand-shuffling is a very common shuffling method, in which the back of a deck of cards is left, the face of the cards is slightly tilted to the right, lying horizontally in the left hand, the four fingers of the left hand hold the bottom of the cards, and the left thumb gently rests on the back of the cards, as shown in the figure. The right hand picks up one-third of the cards behind the left hand card stack, moves them out upward, and then folds one-third of the cards on the back of the left hand card, as shown in the figure. Repeat the above three or four times, and the cards will be washed.

2. Staggered shuffling is an advanced shuffling method, which needs to be practiced frequently to be used fluently. Divide a deck of cards by about half a deck on average, and hold the cards with their backs up in both hands. The card holding method is as shown in the figure, and the cards of the left and right hands are staggered and dropped one by one. Put it on the table or hang it in your hands to shuffle the cards. Beginners should put it on the table to master it.

3. Pick up the staggered cards and stick them in the jaws of the right and left hands, then push the cards into a semi-circular shape with both hands, and relax them with appropriate force, so that the semi-circular cards will automatically fall down, which is very beautiful. Can be repeated several times, the cards will be reasoned neatly and shuffled alternately.

4. Rivru shuffling is a particularly difficult and cool shuffling method. Hold the card in your right hand, put your thumb at one end, put the other three fingers at the other end, and bend your index finger and stick it on the back of the card. Then straighten the index finger of the left hand, put it on the front end of the card with the center of the heart up, and then gently relax the thumb of the right hand so that the lower part of the card falls on the fingertip of the left hand.

put the tip of the left index finger on the back of the left card. The fingers of the left hand are bent, and with the help of the right hand, the cards of the left hand are built. Pick up the top of the left hand card with your left thumb. At this time, the fingers of the left hand should hold the card in the same way as the right hand. Bend the cards in both hands by roughly the same radian, and pay attention to keep the other four fingers bent except the thumb, and make the upper ends of the cards in both hands face each other.

then put your finger out and put it side by side with the other three fingers. At this time, control the strength of the thumb and gradually relax the rest of the fingers. Then the cards will fly together. Fold the cards together with both hands to complete the whole process.
