The challenge of mahjong tiles is to remove two ***272 cards (plum blossom, bamboo chrysanthemum, spring, summer, autumn and winter) from mahjong tiles. Every four tiles are a group, you have 8 seconds to remember them, and then continue to write down a group until all 272 tiles are remembered.

The shape of "bar" is very similar to the number 1, so we can consider converting it into a number with the unit number 1.

One, two, three, four, five, six, seven, eight, nine.

The corresponding figures are:

1 1、2 1、3 1、4 1、5 1、6 1、7 1、8 1、9 1

The coded images corresponding to these numbers are:

Chopsticks, crocodiles, sharks, emcees, foxes, eagles, kiwis, ants, jerseys.

The shape of "cake (cylinder)" is like the number 0, which can be considered as a number with a unit number of 0.

One cake, two cakes, three cakes, four cakes, five cakes, six cakes, seven cakes, eight cakes and nine cakes.

The corresponding figures are:

10、20、30、40、50、60、70、80、90

The corresponding coded images are:

Baseball, ear bell, forest, commander, Wulin, durian, Kirin, Paris, wine bottle.

"Wan" has no suitable image, so we can directly use the number 1-9, and the corresponding coded images are:

Trees, ducks, ears, red flags, hooks, ears, spoons, crutches, gourds and rackets.

Through the above methods, "strips, cakes and millions" can be transformed into corresponding images.

Next, let's look at the "Southeast, Northwest and White" card.

"East" can think of "winter melon";

"South" can think of "pumpkin";

"West" can think of "watermelon";

"North" can be considered as "cup" or "shell";

"China people" can think of "alarm clock";

"Fa" can be considered as "gold ingot" or "gold coin";

"White" can be considered as "whiteboard".
