Although he said it was fine, Dong Qiangqiang knew that it was not really fine. His English was not as good as German. But at this moment, those urgent wisdom that had emerged at countless critical moments appeared again, and he thought of countermeasures at the first time.

Although economics has mathematics, it still belongs to the liberal arts major. It can be different from other liberal arts such as politics or history. These two are usually mostly used to explain their views through words, while most of the knowledge points in economic and financial aspects can be interpreted through pictures and texts.

The first response strategy that Dong Qianqiang set for himself: draw more pictures if you can’t speak!

After explaining the concept of prisoner's dilemma in English, he used the scribing method to list the four results of Nash equilibrium. After explaining the inventory in his mind with his speech and gestures, he racked his brains to deal with the professor's last problem.

The professor didn't know Dong Qiangqiang's mental journey, nor did he know his mentality of fighting against the enemy. He seemed to be quite satisfied with his answer.

Before Dong Qiangqiang could take a breath, the professor threw more economic and financial knowledge test points to him like a flood.

"Please give an overview of Keynes' economic cycle theory."

"Please use cardinal utility theory to analyze consumer equilibrium."

"Please briefly explain the manifestations, causes and possible impacts of the imbalance in money supply and demand."

“What is a liquidity trap?”

"How is the elastic exchange rate defined? Is China now a flexible exchange rate?"

"Please explain the Black-Scholes option pricing model."

...

The professor's problems are difficult and easy. Some of them were carefully prepared by Dong Qiangqiang, but for more problems, he could only say one, two, three in English, and for four, five, six, he could only "can't speak, but he yearns for it."

He felt a sword and sword in front of him. He didn't dare to be careless, so he could only concentrate on countering the moves.

While blocking the opponent's "attack", he quickly set a second adaptation strategy for himself: if you can't speak English, you will immediately speak in German, and you will definitely not say "I can't", and I can speak all the contents. My language must have flaws, but I can use all the languages ​​I have mastered to prove that I have indeed learned the questions you asked. Otherwise, if you can't speak German in English, you will think you are a liar. If the doctor is picky, then go fucking, and the other party will say whatever the other party likes to say. I am not a master's degree in English, so it would be nice to be able to speak in German.

This strategy was determined, and Dong Qiangqiang suddenly felt that he had liberated himself. Although the confrontation with the professor made him sweat, as soon as he opened his heart, his mind became flexible and he became more comfortable and smooth.

At first he was worried that the two would correct the problem again that they did not speak English. Later, he found that the "Big Back Head" did not raise any questions about his explanation, and the doctor just asked a few questions without any pain and was easily resolved by Dong Qiangqiang.

Dong Qiangqiang was quite surprised by the other party's silence. The other party could not have understood English. He was thinking to himself, and a thought suddenly flashed through his mind: Could it be that these two people don't understand economic professional content? If so, it would be too funny.

But I don’t know if it’s an illusion, but the “big back head” always gives him a gloomy feeling. It makes people feel very unfriendly, like an old computer analyzing Dong Qiang’s words at all times.

In the following time, Dong Qiangqiang and Professor passed seven or eight more knowledge points. As his previous guess, neither of the examination committee mentioned that Dong Qiangqiang had to answer questions in English, which made Dong Qiangqiang more confident and confident.

Just as he was ready to answer the next question asked by the professor, the professor suddenly put down his pen and said to him kindly: "Please go outside the door first, we will invite you in again in five minutes."

Dong Qiangqiang was still in a state of fighting. Before he could enjoy his whole life, he met the opponent Mingjin withdrew his troops. He was both happy and disappointed, so he could only nod and thank him.

Just as he turned around and was about to walk out of the office, the "Big Back Head" who had been silent for a long time suddenly said, "I have another problem."

"Big Back Head" didn't say a word before, but Dong Qiangqiang felt abnormal. Now that he heard the other party say this, he immediately turned around and looked at him, just hitting the "Big Back Head" with a slightly gloomy and provocative look.

"Please say it."

"When you mentioned the exchange rate just now, you said that China is not using a fixed exchange rate. Can I understand that China has always adopted a floating exchange rate? After all, there are only two exchange rate models in the world now." The "big-back head"'s eyes were sly, "But I also saw that China's RMB and the US dollar have been bound together in recent years. The equivalent value of 1 US dollar is always hovering between 8 and 8.5 yuan, and the United States also always says that China is a exchange rate manipulator. What do you think about this?"

Dong Qiangqiang had discussed the topic of China's exchange rate with his teachers and classmates many times when he was studying in the preparatory course. He knew very well that exchange rate was one of the Chinese things that many Germans paid special attention to, and it was also the most popular content for many American politicians.

Generally speaking, economics in colleges and universities usually do not rise to the level of a specific sovereign state (Professor Thomas did not mention similar issues throughout the whole process), but now the other party takes the initiative to mention the country, Dong Qiangqiang can't help but become sensitive and alert.

"This is how I understand the question you mentioned." Dong Qiangqiang quickly passed his reply in his heart, and after confirming that he had not made any mistakes, he slowly replied, "China is currently the largest developing country in the world. Its economic development determines that whether it is a simple fixed exchange rate or a floating exchange rate is not suitable for its national conditions. Especially after the Asian financial crisis in 1997, Asian countries were generally deeply trapped in the quagmire of economic recession. After fully considering the world economy and China's actual national conditions, the smart and wise Chinese people finally chose a managed floating exchange rate system as China's national exchange rate policy."

"Is the so-called 'managed floating exchange rate system' a transaction rate manipulation?" "Big back head" pressed forward step by step with malicious intentions, "After all, the US dollar has not changed against the RMB, and this is definitely not a floating exchange rate. This is a fixed exchange rate."

When the female doctor heard the question "Big Back Head" and seemed to be interested, her body was straight and staring at Dong Qiangqiang intently, her face full of curiosity.

Dong Qiangqiang had already understood the opponent's small plan at this time, and couldn't help but sneer in his heart, thinking: You show your power in the first half, it's my turn in the second half.

He has discussed this topic with others many times in the preparatory department and has become familiar with it. He coughed and his throat immediately, and answered in German without being humble or arrogant.
