After explaining JQK, Instructor Wu asked curiously: "What do spades, red peaches, plum blossoms and squares mean?"

"This question is well asked, and there are many explanations. One of them is: the four colors represent four major industries in European society in the Middle Ages, among which spades represent spears and symbolize soldiers; the red peaches represent red hearts and symbolize priests; the plum blossoms represent clovers, symbolize agriculture; the squares represent bricks and tiles, symbolize craftsmen.

Another saying is that these four colors are derived from the patterns of the artifacts used in ancient European divination;

Of course there are many other statements, and different explanations are available in different countries and regions.”

"Then why is it 54 cards?"

Li Fan smiled and said, "Instructor Wu asked this very well. One of the explanations is based on the calendar.

The king represents the sun, the little king represents the moon, and the other 52 cards represent the 52 weeks of the year; the four colors of red peach, square, plum blossom, and spades symbolize the four seasons of spring, summer, autumn and winter respectively; each color has 13 cards, indicating that each season has 13 weeks.

If J, Q, K are regarded as 11, 12, 13 points, and the king and the little king are half points, the total number of points for a deck of playing cards is exactly 365 points. In leap years, the big and small kings are calculated as 1 point, with a total of 366 points.

Some experts believe that the design and invention of playing cards are closely related to astrology, divination, astronomy, and calendar.

Of course, there are various other explanations.”

...

A "academic discussion" about playing cards has finally ended. Instructor Wu's always serious facial expression has long disappeared. At this time, she was listening with her ears up and listening seriously.

Li Fan put away the playing cards and said, "Well, that's all for today's academic discussion on playing cards. Don't underestimate this deck of playing cards. It also carries a strong historical atmosphere and is completely the crystallization of human wisdom."

Instructor Wu nodded and said, "Well, that's right!"

Li Fan opened the drawer, threw the poker in, and quietly raised his eyebrows to his roommates. Is Brother Fan reacting quickly?

Ma Qiang secretly gave Li Fan a thumbs up, thinking that he was awesome, easily resolve the crisis!

"Li Fan!"

"Instructor Wu, what instructions do you have?" Li Fan turned around and said.

"Go downstairs and run around!"

"Ah? Ah! OK!"

Li Fan put on a hat, tied a belt, and followed Instructor Wu downstairs in a regular manner.

Instructor Wu said as he walked: "The upper beam is not straight and the lower beam is crooked."

Li Fan followed and nodded, "Try not to be crooked in the future."

"What does it mean to try? Oh by the way, you explained it all by JQK, you forgot to explain it, what does it mean?"

Li Fan took the opportunity and said, "Instructor Wu, how many laps will I run tonight?"

"Oh, bargain?" Instructor Wu stopped and said with a smile.

"No, how dare I! Do I run three laps? I really can't run anymore, I'm tired in the morning."

Instructor Wu narrowed his eyes and asked again: "What does A mean?"

"How many laps will I run?"

"Okay, I won't ask anymore, go run away. You are the squad leader, please consider it. I'll be waiting for you here tonight."

This one comes again!

Li Fan started the long-distance running again, panting and running on the playground.

Instructor Wu sat on the high platform, lowered his head and turned on his phone to Baidu. What does A mean? After searching for a long time, he didn't even search for a shadow.

Instructor Wu looked up and shouted to Li Fan: "Li Fan, what does A mean?"

Li Fan sighed: "I don't know!"

"Then you keep going."

"Instructor Wu, when are you planning to let me run?"

"Dawn!"

"ah?"

At this time, several figures suddenly popped up at the entrance of the playground. After chatting for a few words, they shouted to Li Fan: "Li Fan, stop running away, we are here to pick you up."

Li Fan looked back and found that it was Zhou Kai and others. He walked to Instructor Wu and said, "Sorry, Instructor Wu, I have a job and leave first."

Instructor Wu asked again: "What does A mean?"

Li Fan shook his head and said, "I really don't know."

Bang!
