Speaking of the taboos of using chopsticks, Feng Junzi said with a gaze: "The most important thing to pay attention to when using chopsticks is that you just put in incense and offering sacrifices on the dining table is that you cannot guide the way. You cannot point the chopsticks at others when speaking. You cannot knock on the dishes and bowls when eating. You cannot use chopsticks to hit the dishes, because this will disturb others' meals. In addition, when beggars beg for food, they sing the lotus when they fall. You cannot turn the world around with chopsticks. You cannot turn the world upside down or hold the chopsticks in the opposite direction. You must also be careful not to lick the head of the chopsticks with your mouth... When putting chopsticks, you must pay attention to put the tip of the chopsticks forward and put it on the right side of the bowl... You can also put the left side, but be careful not to put it horizontally and vertically on the bowl..."

Lin Zhenzhen: "It turns out there are so many rules, but what you said makes sense."

Chang Wu: "When you talk about chopsticks, I remember something about chopsticks. A while ago, a Japanese woman came from Longwangtang Police Station. She took a pair of ivory chopsticks and asked the police officers of the police station to help find someone. I asked if there were any elderly people over 60 years old who had seen these chopsticks. Do you think it was strange?"

Lin Zhenzhen: "It's really amazing in the world. Do you often encounter such interesting things as policemen? An elderly person over 60 years old? This is interesting. It's been sixty years since the War of Resistance Against Japan. Does this have anything to do with the War of Resistance Against Japan?"

Chang Wu: "Maybe it was related to the events during the War of Resistance Against Japan, but the Japanese woman said nothing. She left a contact address for the police station at a hotel in Binhai, but later the police called to contact him, and the woman suddenly left."

Lin Zhenzhen: "You really help her contact, oh I understand, you are considered foreign guests at least. You guys who are looking inward and look outward can't even take care of serious things, and you still care about Japanese girls' other things. If this is a Chinese commoner who takes a pair of chopsticks to the police station, it's a big deal that someone can pay attention to him... Brother Chang, I'm not talking about you, I heard Feng Junzi say you are a good policeman..."

Japanese woman? Longwangtang? When Chang Wu and Lin Zhenzhen were talking to each other, Feng Junzi suddenly thought of something. Some time ago, when he met Taomuling on a rainy day in the coastal area, Taomuling was about to take a taxi to Longwangtang. Could it be that the Japanese woman Chang Wu mentioned was Taomuling? Thinking of this, Feng Junzi interrupted and asked: "What is the origin of that oriental girl? How did the police from Longwangtang Police Station know about this incident? "

Chang Wu: "I don't know what the origin is. Later, the woman left without saying hello. It's just that things are strange and everyone comes to talk about it."

Feng Junzi said lightly: "I guess that woman is very young and beautiful, so the police officers in your police station remember not to forget it. Is that true?"

Chang Wu: "Who is really saying anything, but you are right. It is said that the woman is very beautiful. She saw several small police officers who had just graduated from our police station drooled."

Feng Junzi was already 80% sure that the person Chang Wu said was Taomuling. But Taomuling was hiding at his house now. Feng Junzi was really unwilling to say this matter in Chang Wu, especially in front of Lin Zhenzhen. He saw that Chang Wu could not say anything new. He thought that he knew only a limited amount, so he did not ask. But Lin Zhenzhen was obviously interested and kept asking Chang Wu what new stories there were in the Public Security Bureau. The following passage attracted Feng Junzi's attention again.

"There is not much new when it comes to news. We just file cases, solve cases, and catch bad guys all day long. But next month, our branch has something new. We want to cooperate with the newly opened psychology major of Binhai Normal University and introduce psychological technology into modern criminal investigation practice."

Lin Zhenzhen: "I should have done this a long time ago. I watched police and gangster movies on TV. The police always scared people when asking about cases. Not to mention criminals, I even know."

Chang Wu: "It's not all about TV. We police also need to learn criminal psychology in police academy, but they don't use it much when investigating cases."

Lin Zhenzhen: "Whose idea is this?"

Chang Wu: "It's interesting to say that it's a sudden idea of ​​a supervisor in the city... This leader rarely went home for dinner, so he had time to watch TV with his wife. He happened to see a foreign program introducing criminal investigation. He saw foreign psychologists decomposing the subtle facial expressions of the suspect when answering questions, so he inferred the authenticity of the suspect's answers and the real crime scene at that time. The leader became interested at the moment and instructed our branch to introduce this new technology to pilot it."

Feng Junzi interrupted again at this time: "Then why do you have to cooperate with Binhai Normal University? As far as I know, their psychology major has just been open for a long time and they should not have much experience, especially the aspect of criminal psychology is different from educational psychology."

Chang Wu: "You don't know this anymore. The wife of the city's leader is the deputy director of the Department of Psychology at Binhai Normal University."

Lin Zhenzhen: "So that's the case. Academic research also depends on nepotism."

Feng Junzi: "Are there any preparations for Normal University?"

Chang Wu: "The Normal University also attaches great importance to it. It is said that I have contacted a very famous psychology master in the United States. The United States will also send a psychology expert to assist in this topic."

Feng Junzi: "Is that American expert here?"

Chang Wu: "Not yet, I will arrive next month."

At this time, Feng Junzi felt more and more coincidental. What Chang Wu said and what Tao Mu Ling said seemed to be the same thing. This American psychology expert should be Tao Mu Ling, that is, the Japanese woman who found the Longwangtang Police Station with a pair of chopsticks. Although Chang Wu didn't know that these two people were the same person, Feng Junzi was already like a mirror. There are really too many coincidences in the world, and there are many unexpected things as smart as Feng Junzi.

...

When Feng Junzi came home in the evening, Taomuling was actually preparing midnight snacks for him. Feng Junzi also had three meals a day, but compared to other people, these three meals were a bit delayed, namely lunch, dinner and midnight snacks. Taomuling had just stayed here for two days and had already understood Feng Junzi's habit, which made Feng Junzi feel a little embarrassed and happy.

Feng Junzi thought alone in the study for a long time. When it was the midnight snack, he finally decided to say something to Taomuling. He held the chopsticks and asked in a pondering manner: "Taomu, you took a pair of ivory chopsticks a while ago and asked someone to identify them. Can you show me those chopsticks?"

A look of suspicion flashed in Taomuling's eyes: "How did you know?"

Feng Junzi thought about it and thought it would be better not to lie to people like her: "When I was having dinner today, a friend who worked in the Public Security Bureau mentioned that a few days ago, a Japanese woman went to Longwangtang Police Station to find someone with a pair of chopsticks. If I remember correctly, when I met you that day, you happened to go to Longwangtang as well. I guess this person is you."

Taomuling seemed to breathe a sigh of relief: "You guessed it is right, that person is me. I told you the origin of these chopsticks the night before yesterday. Are you still so curious?"

The night before yesterday, Feng Junzi smiled bitterly. He didn't remember what happened the night before, but Taomuling now said that the origin of the pair of chopsticks had been told. He decided not to talk about what happened the night before, and said, "Of course I'm curious, just let me take a look."

Taomuling turned around and walked into the bedroom, brought a small wooden box, and handed it to Feng Junzi. The rectangular wooden box was antique and exquisite, emitting a long-lasting atmosphere. Feng Junzi opened the wooden box and took out a pair of white chopsticks with teeth. These chopsticks looked carved from ivory, slightly smaller than the chopsticks on the dining table, but the shape was the same, all with round front and square back - this is also the meaning of Chinese chopsticks being round in the sky, round outside and square inside. In the square handheld part, exquisite flowing cloud-shaped patterns are also very delicately carved.

When Feng Junzi's hand touched the chopsticks, he had a very strange feeling. This feeling was like a very weak, undetectable electric current spreading throughout his body at that moment. Suddenly he felt the chopsticks tremble slightly in his hand. Of course, this was just an illusion of his illusion. This was a pair of items from some eras. Although these ivory chopsticks were very delicate and precious, they were just ordinary items in the old society. But in Feng Junzi's hand, there was a very special feeling. Feng Junzi suddenly felt that the chopsticks seemed to have a strong desire - something to tell him.

"Can you hand over these chopsticks to me tonight?"

Taomuling seemed to be unprepared for the sudden request made by Feng Junzi, and asked in a stuttering manner: "You, what do you want these chopsticks for? Do you want to sleep with it at night?"

Feng Junzi: "Do you remember that I suddenly knocked on your door last night? Actually, I did hear the sound at that time, and the sound came from somewhere in your room. I now suspect that it was the sound made by these chopsticks, but this sound is just that ordinary people cannot hear it under normal circumstances."

Taomuling: "Sound? You said that these chopsticks will make sounds at night? But ordinary people can't hear them! Then what sound do you say?"

Feng Junzi: "The sound of waves, guns, and the crying of women and children."
