Looking at the series of search results displayed on his mobile phone, Tian Yinong didn't know what to say for a while, the first search result was a report about Tao Li's MOOC, and then there was an interview with him at the daily base camp and the Yangtze Evening News, etc., no wonder Tian Yinong felt as if he had seen Tao Li when he first saw it.

It turned out to be really that Mr. Tao!

"What, Lao Tian, do you know the teacher just now?" Hearing Tian Yinong's exclamation, Zhang Xiaobin asked curiously. It's the first time we've met, so how can we know each other? And I didn't recognize him at the beginning!

"You forgot? It's the super powerful high school math teacher I told you last time, Mr. Tao!" Tian Yinong didn't say that he knew Tao Li, but he also had a younger sister who had just entered high school at home, and when he came home on National Day, his sister was so obsessed with Tao Li, opening her mouth and closing her mouth to a male god.

Especially at that time, Tao Li's MOOC had just been launched, and the first phase of the live Q&A activity had just been completed, and the momentum was at its peak, and many high school students from other provinces and cities were able to get to know Tao Li by taking this opportunity. Tian Yinong watched the video of Tao Li's lecture for more than ten minutes. It's really much better than the rest of the teachers, but more than a month has passed, and he hasn't remembered it much, so he didn't remember who Tao Li was just now.

"It's that tall and handsome math teacher? Fuck! I seem to be really right when you say that, that younger brother just now is really handsome!" Zhang Xiaobin patted his head and said with a sudden realization.

"If my sister knew that I met Teacher Tao herself today, I wouldn't be envious to death!" Although Tian Yinong does not chase stars, Tao Li is also a standard "Internet celebrity" in the education industry, and it is still wonderful to think about it now.

"When you say that, when he comes tomorrow, I have to take a good photo with him and leave a souvenir or something. Zhang Xiaobin also rubbed his hands and said excitedly.

On the other side, Tao Li and Chen Tianxiang, who finally squeezed onto the subway, were on their way back to the hotel, but Chen Tianxiang kept laughing all the way, which made people wonder if they had a brain.

"Teacher Tao, ah, no, it's a junior brother, how are you doing in the School of Mathematics of Yan University?" Chen Tianxiang felt very happy when he thought of the trouble he had just made.

"Oh, you're not Yan University, are you a top student from Qingbei University opposite?" Chen Tianxiang is now frantically adding drama to himself, as if he has never encountered such a funny thing in his life.

"I said, Mr. Chen, you're enough, aren't you tired of laughing so far? If you hadn't suddenly had to go to the toilet, would you have encountered this kind of thing?" Tao Li said angrily at Chen Tianxiang, who was holding his stomach.

"Whoever made your hands itch, you have to do the question, now it's okay, do a question, and send two senior brothers, hahaha. Speaking of this, Chen Tianxiang didn't hold back again, covering his mouth and smirking on the side. Fortunately, there are not many people on the subway at this point in time, otherwise he would have to be considered mentally ill.

"Not to mention anything else, is the basic knowledge reserve of the current graduate students so poor? The third-year graduate student of the Department of Physics of Yan University does not even know such a simple mathematical problem, and how can he study in the advanced field of physics without strong mathematical knowledge as a support?" Speaking of this, Tao Li couldn't help frowning.

"Colleges and universities are expanding. It has extended from undergraduate to graduate level. Like my time, it was very good to meet an undergraduate, but now, the streets are full of college students, and there are not a few master's students, and it is estimated that doctoral students are relatively rare. Chen Tianxiang put away his joking attitude and said.

Originally, it was a university that cultivated talents, but because of the expansion of colleges and universities, higher education has become an industrial chain that circles money, which even the highest universities in China, Yenching University and Qingbei University, are not exempt.

"Forget it, I can't think about it so much. Tao Li sighed, not knowing what to say for a while. Under the current education system, even if you want to make some changes, it is powerless, and in a certain sense, the expansion of colleges and universities has indeed sent a lot of talents to China.

There are two sides to everything, and you can't keep staring at his shortcomings.

After the two of them returned to the hotel, it was already more than eleven o'clock at night, and after a simple wash, they went to bed directly. The next morning, Tao Li, as usual, got up before seven o'clock, and when he was so old, he didn't have the habit of sleeping early, so whether it was a working day or a rest day, he must have gotten up before half past seven at the latest.

"Teacher Chen, I'm going to Yanda, do you want to go together?" Looking at Chen Tianxiang, who was still lying on the bed, Tao Li called softly.

It's just that Chen Tianxiang didn't speak, but turned over, turned his back to Tao Li, and then picked up the quilt and covered his head.

Tao Li sighed helplessly, it seemed that he couldn't get up for a while, there was no way, he could only go to Yanda alone. After all, Tian Yinong and Zhang Xiaobin promised that they would have to participate in the competition tomorrow, and if they went in the afternoon, they might not be able to come back until late in the evening, which is not conducive to tomorrow's competition.

Tao Li went out, and after having some breakfast outside, he got on the subway and walked in the direction of Yanda. Before leaving, I didn't forget to send a WeChat message to ask Tian Yinong about them, but fortunately, the two graduate students got up early and replied to him quickly.

According to the appointed time, Tao Li just walked to the main gate of Yanda and saw Tian Yinong and Zhang Xiaobin waiting for him there.

"I'm really sorry, I have to trouble Mr. Tao for you to run. Tian Yinong hurriedly stepped forward and said embarrassedly.

"It's nothing, just take it out to breathe, let's go, I'll finish talking to you early, and I'll go back early." Tao Li said indifferently.

"Teacher Tao, you are the famous high school teacher on the Internet, can you take a photo together for a while!" I didn't notice it last night, but if I looked closely today, Tao Li really looked like a dragon and a phoenix among people! Zhang Xiaobin said urgently.

"I'm not as famous as you say. Tao Li didn't expect that far away in Yanjing, there were actually people who could recognize him.

"Done! I'll talk about it after I finish talking about it. After getting Tao Li's promise, Zhang Xiaobin said happily.

After coming to the classroom last night, Tao Li began to explain the problem solving steps on the blackboard to me from the beginning, and when they encountered mathematical theories that they did not understand, Tao Li would also take the trouble to give them literacy and explain the relevant knowledge points to them in detail. In this process, Tao Li can also review his previous knowledge.

It took more than an hour to finish this question, and Tao Li also took a group photo with them after talking about the topic as he said before.

"Mr. Tao, it's still early, why don't I take you to visit our laboratory, I still have some questions for you at noon." Tian Yinong wiped the blackboard clean and said sincerely to Tao Li.
