Xixi National Primary School is located in Qingpu urban area, and the school was originally the Li Family Ancestral Hall.

Two old pine trees that have not known for hundreds of years stand on the campus like two ancient patron saints.

Dai Chunfeng stared at one of the old pine trees.

Seeing Dai Chunfeng shaking his head, Yu Ping'an asked, "What's wrong with Seating?"

"I don't know if the old trees that have been hundreds of years can be preserved." Dai Chunfeng sighed, "If the country is in trouble, even the plants and trees will suffer."

The seat suddenly felt sad and sad, and Yu Ping'an didn't know how to answer the conversation for a while.

"Whose class?" Dai Chunfeng pointed to a classroom not far away and asked.

"It's Class 2." Yu Ping'an thought for a while, "It should be Xiao Mian in class now."

When Dai Chunfeng heard the name "Xiao Mian", a smile appeared on the corner of his mouth, and he was a little amused.

"Cheng Wufang", "Shui Drop", "Blue Bird", "Mr. Xiao", less than two years after joining the Secret Service, Cheng Qianfan has had so many pseudonyms and code names.

"Let's go and listen to this Instructor Xiao's class." Dai Chunfeng raised his hand and said.

"Zhu, Xiao Mian is now using the name Yuan Guoan." Yu Ping'an reminded him.

"I understand." Dai Chunfeng nodded.

The students in the Qingpu Special Training Class will only know that their instructor’s name is Yuan Guoan.

Only a small number of other important instructors in the Qingpu Special Training Class knew that this instructor was "Xiao Mian".

The Japanese side has more or less known about the existence of the Shanghai Special Information Group.

Cheng Qianfan discussed with Dai Chunfeng that Xiao Mian's identity should also be shown appropriately to confirm the existence of this identity.

Sometimes, if an identity is always hidden, the enemy will be extremely suspicious and the search will be expanded, which is not a good thing.

The identity of Xiao Mian was confirmed, and some of Xiao Mian's information had a certain chance of spreading it, but it was actually a protection for Cheng Qianfan.

Of course, confidentiality must be kept confidential, so only some important instructors will know about Xiao Mian.

...

This is a tile-house classroom.

The classroom was filled with students.

The Qingpu Special Training Class has more than 400 students, all of whom are young dropouts, intellectuals and students found by Dai Chunfeng from the Jiangsu-Zhejiang Action Committee’s Rangers.

More than 400 students were divided into five classes, ranging from 80 to 90 people in each class.

Dai Chunfeng and Yu Ping'an came outside the classroom and stood at the window and looked inward.

I saw a lieutenant colonel in his thirties with a beard and a scar about three or four centimeters long on his right cheek. He was standing in front of the podium in a straight military uniform and making a generous voice.

"What is the first creed for agents to successfully lurk and survive?" Cheng Qianfan turned around and wrote three words on the blackboard: Reasonability!

"Where did he get his military uniform?" Dai Chunfeng asked.

"It was specially requested by Instructor Yuan. He must wear military uniforms." Yu Ping'an whispered, "This is Sheng Shuyu's military uniform, and he took it away."

Dai Chunfeng glanced at Cheng Qianfan, but he did not criticize him after all. He knew Cheng Qianfan's resume. Finally, he studied the sixth infantry department of CSKA. This kid should have been eager to kill the enemy on the battlefield.

In addition, only in such an environment can Cheng Qianfan have the opportunity to wear his favorite national military uniform openly.

This kid.

Fortunately, Cheng Qianfan's grandfather, Mr. Gu Zhi, sent him back to his hometown in Jiangshan from Huangpu Road, Nanjing.

Dai Chunfeng was also happy. The National Army had a lack of a school official, and the Secret Service had an additional resourceful ace agent.

"Yes, rationality." Cheng Qianfan nodded, "Being behind enemies surrounded by enemies, you must first have a hidden identity, and then, everything you do must match this hidden identity, which is rationality."

As he said that, Cheng Qianfan glanced at the students and he casually ordered one of them, "Yu Ailin, come and play a hawker selling needles and threads."

As he said that, Cheng Qianfan waved his hand, and some soldiers carried a shoulder pole, two baskets, and some other things came in and placed them on the ground.

Yu Ailin came to the podium, but he didn't do anything immediately.

Instead, he carefully tinkered with the items on the ground, then carried two baskets with a shoulder pole, picked up a black towel and put it on his neck. After thinking about it, he bent down and turned it over from other items and found a gourd and tied it to the edge of the basket.

As we walked, the iron nails on the gourd heads collided with the basket, making jingling sounds, and shouted from the mouth of the "hawker": Needle and thread, sell it at a cheap price.

Watching Yu Ailin carrying a shoulder pole, a basket, and a hawking hotly.

"Stop!" Cheng Qianfan called to stop.

"Instructor Yuan." Yu Ailin looked at the instructor's gloomy face and felt a little at a loss. He felt that his performance was excellent.

Cheng Qianfan stared at Yu Ailin, and the other party was at a loss. Then he took off the gray towel around Yu Ailin's neck.

"This towel." Cheng Qianfan picked up the towel and said to the students, "Please note that this towel has two uses. One is to wipe sweat on your neck like Yu Ailin just now."

As he said that, he wiped his sweat with a black towel without caring.

Then, he put the towel on his shoulder, turned his head and took a look, and moved the position of the towel.

Then bend down and carry the shoulder pole, basket, and stand up.

The students immediately understood the second purpose of the towel mentioned by Instructor Yuan. The towel is placed under the shoulder pole, which can reduce the friction between the shoulder pole and the shoulder.

"Of course, some vendors who walk around the streets will sew two more puddings on their clothes on their shoulders, which can also reduce the wear of clothes and protect their shoulders." Cheng Qianfan said.

As he said that, he raised a shoulder pole and moved the towel on his shoulder a little longer, one end slightly shorter.

"This is the most correct one." Cheng Qianfan said, grabbing the towel on the slightly longer end, just enough to wipe the sweat on his cheeks.

In this way, it can not only protect the shoulders, but also play the original role of a towel.

"Don't underestimate such small details." Cheng Qianfan looked at the students, "If you want to pretend to be a vendor who goes around the streets and find out about the news, and then pass by me, these small details are enough to expose you and be seen through me at a glance."

They are all intellectual young people, and in addition to high school students, there are two college students. Some people listened very seriously to the details that Instructor Yuan said, while others did not care about them.

Cheng Qianfan saw the careless expressions of some people, and he knew what these people were thinking.

They are all educated young people with high education. They joined the Rangers and the Secret Service to fight the Japanese. Even if they lurk in enemy-occupied areas in the future, their hiding identities are mostly decent and they will not do such jobs as hawkers who walk around the streets, so they don’t have to worry about it at all.

Dai Chunfeng stood outside the window, seeing the performance of some students who were not serious about the suspension of classes, and snorted in his heart:

A good person is low.

"There is another point, the hawking voice of the hawkers selling needles and threads is not just a casual voice like Yu Ailin just now."

Cheng Qianfan said, carrying a shoulder pole and a basket, walking around the podium, shouting at the top of the voice:

"Thimble needle awl needle thread brain, tobacco pipe and fire sickle embroidered purse, mirror oil box comb scissors, foreign socks and towels are picked..."

The students looked at their instructor in shock.

The lieutenant colonel of the Kuomintang, who was standing in front of the podium, was so majestic and powerful that he was not angry, lowered his shoulders, with a smile on his face, and finally shouted: "Buy it at a low price and sell it at a low price-"

Instructor Yuan casually pointed to a student in the front row, and the person stood up.

Instructor Yuan also went up to greet him enthusiastically: "You pick it up and pick it up, and you won't be bothered if you don't buy it! Look, open your eyes, and be sure to use it!"

This sings sound, the higher the sings.

If it weren't for Instructor Yuan's official uniform, his distorted beard and scars on his face, he would have been a hawker who was wandering around the streets.

...

"Good boy." Dai Chunfeng looked outside the window with relish and admired.

Yu Ping'an also had a smile on his face, and this is also his student.

"In addition to rationality, there is also an extremely important point." Cheng Qianfan said, "Memory!"

He pointed to his head, "Remember the people and things around you as much as possible, remember the surrounding environment, and when you find that there are changes in your surroundings and your cognition, even if it is a more subtle and inconspicuous change, you must be highly vigilant."

Cheng Qianfan looked at the students, "The last thing I want to talk about today is what the most correct reaction you should make when you realize that something might be wrong, or you suspect someone has a problem."

As he said that, Cheng Qianfan pointed to a student, "Lei Jialiang, come here."

"Yes!" The students wearing glasses walked to the podium.

Cheng Qianfan took out two pages of paper from his body.

"The two pages are exactly the same, and it is a plot I set." Cheng Qianfan said, handing one page to the students under the podium, allowing them to circulate, and giving another page to Lei Jialiang. "In two minutes, after reading it, let's make a comeback and let's act in a play."

"Yes!" said Lei Jialiang.

This is a small story. A is an agent of the Secret Service. He was ordered to join B, but B has already treason.

A realized from clues that there was something wrong with B.

"Time is up." Cheng Qianfan, who had been looking at his pocket watch, said, and he took the page of paper from Lei Jialiang's hand.

...

A: Why are you late?

B: Don’t mention it, when I encounter a Japanese arresting people on the street, I have to take a detour in order to avoid it.

A: Japanese?
