The footsteps and laughter of "stepping on the footsteps" slowly approached the third class of the first year of high school.

The whole class was on standby, and no one dared to make any small movements or whispers.

Zhang Xiao, the head teacher, stood at the door of the classroom, ready to welcome Professor Yang's arrival.

Soon a group of people came to the door of their classroom.

Professor Yang and the director of the school walked in the front, and several teachers walked behind.

Zhang Xiao greeted him with a smile on his face: "Uncle Yang!"

"Hey, Zhang Xiao!" Professor Yang replied with a smile on his face.

Zhang Xiao and Professor Yang have known each other for a long time, and they may still be related.

Professor Yang was wearing a white plaid shirt and suit trousers, and was about 50 years old, with black hair still very thick and no signs of baldness. His figure is not out of shape, and it can be seen that he usually has the habit of exercising.

After the two exchanged a few words at the door of the classroom, Zhang Xiao walked into the classroom first, facing the classmates with a smile on his face: "Students, please applaud and welcome Professor Yang." ”

"Bang Bang!"

Neat and loud applause resounded throughout the classroom.

Professor Yang waved in to applause.

He walked straight to the podium and waved his hand to signal his classmates to stop applauding.

"Students, I'm glad to be here to share my knowledge with you. ”

Professor Yang always had a kind smile on his face.

He took out the USB flash drive he had brought, copied a PPT from the USB flash drive and put it on the computer on the podium.

Zhang Xiao helped to pull down the white curtain hanging on the blackboard.

The projector casts the PPT content on the computer onto the white screen.

The headline of the PPT is: The Origin of the Universe: The Big Bang.

"The Origin of the Universe!" I'm sure many students should be interested in this. Professor Yang said, "Let's take a look at this picture first......

The school director and several teachers sat at the back of the room with a stool. There is also a male teacher who keeps taking pictures with a camera, and the photos taken today will be posted on the school's official website to promote them.

At the end of a class, even the most naughty students don't dare to make a guess, after all, there are several pairs of eyes staring at the back of the classroom.

After Professor Yang finished the lecture, not only the whole class applauded, but even the teacher-level director at the end of the professor also stood up and applauded.

The short, fat director scurried from the end of the classroom to the head of the classroom with a big belly.

The director smiled at the students and said, "Our Professor Yang has not only made great achievements in physics research, but also has studied Go for many years. In the amateur world of Go, it is also a well-known big man. Do you want to ask Professor Yang for advice on Go? ”

"Yes!"

The classmates shouted in unison, in fact, few of the students in the class knew Go, and no one was interested in Go. But every time you are playing, the students still understand this truth, so you have to cooperate with the director.

Due to the crowded desks in the classroom, the grade director took everyone to the living room.

A space had already been made in the middle of the parlor, and the chess table and chessboard had been set up.

As soon as Professor Yang saw the chessboard, he became addicted.

He walked over to the chess table and said to the students around him, "Students, do you know who invented Go?"

"I know!" Liao Jieming hurriedly replied. "Go was invented by Emperor Yao. ”

Professor Yang nodded at Liao Jieming, "What this classmate said is right, the pre-Qin classic "Shiben" records that Yao made Go, and Dan Zhu Shanzhi. However, this statement was only a legend at the time, and the Tang Dynasty man Pi Rixiu said in his "Yuan Yi" that Go was actually created by a group of columnists during the Warring States Period. As for whether it is true or false, it is impossible to verify it now, but in any case, Go was invented by our Chinese nation, and we should be proud of our nation. ”

The director chimed in, "Yes." Professor Yang is right, Go is the quintessence of our Chinese country, and we should continue to pass it on. ”

"Now that the chessboard is set, let's play a few games. Professor Yang sat on the chair next to the chess table, and as soon as he saw the chessboard, he couldn't help but want to play chess, "Come, who plays chess with me, do you volunteer?" Or, Director Huang, you will take the lead. ”

Professor Yang raised his eyebrows and looked at the grade director.

The level of the director of Go is only the entry level, he doesn't want to lose face in front of his students, he pushed Liao Jieming up, and said: "Professor Yang, let's let Liao Jieming from the third class play a game with you, Liao Jieming once participated in the City Youth Go Cup Competition, and also won the third place. ”

"Oh. Have you ever participated in a Go competition?" Professor Yang looked at Liao Jieming with interest.

"Yes, Professor Yang. "I have been practicing Go since I was a child, and I have studied many chess games and genres. ”

"Come, sit down, and let's have a fight. Professor Yang motioned for Liao Jieming to sit down.

Liao Jieming sat respectfully across from Professor Yang.

"For the sake of fairness, I'll let you have two sons," Professor Yang said, "You hold the black son, and I hold the white son." ”

Of course, Liao Jieming knew that there was a big gap in strength between him and Professor Yang, so he also agreed to be given the second son. He used a very standard gesture to put a piece on each of the diagonal stars on the chessboard.

Then it was Professor Yang's turn to play white.

There is a proverb in Go, "Golden Horn and Silver Border Grass Belly", the value of the four corners is the highest, the edge is second, and the hinterland in the middle of the chessboard is the lowest because it is ventilated on all sides and is not easy to enclose the air.

Liao Jieming grabbed the corner as soon as he started, and every step was orderly.

But in the middle game, after playing more than 100 hands, he began to sweat profusely, at this time Professor Yang was already fifteen eyes ahead of him, and he had no possibility of turning the game, and the chess strength between him and Professor Yang was still too far apart, even if he was given the second son, he was still easily won by Professor Yang.

"I lost. Liao Jieming had no choice but to bow his head and admit defeat.

"You're playing a pretty good game. I'm just more experienced than you, and you're a good talent in Go, so maybe you'll be able to beat me soon after studying a little more chess. Professor Yang encouraged.

"Thank you, Professor Yang, for the compliment!" Liao Jieming said happily, he really took Professor Yang's kind words as a compliment.

Professor Yang stood up from his seat and said to the students who were watching the chess around him, "Come, you guys, I will watch the chess next to me." ”

"Uncle Yang, aren't you going down?" asked Zhang Xiao.

"The next one is too much brain-draining, so I'll slow down and give up a place for the student. Professor Yang said. In fact, he felt that it was not interesting to play chess with a chess player who was too far away in strength, and the game of chess he played with Liao Jieming just now could only be regarded as a boring game of chess, and every move and every intention of the opponent was seen through by him, and he felt that it was not interesting at all, just like an adult and a child fighting.
