My Identity As A Schoolmaster Has Been Exposed

Back in the car, Han Honghu's car slowly left.

Wen Ruohuai directly gave orders to Han Honghu, saying: "Xiao Han, use the best decoration materials for Teacher Xu's house!"

From "good use" to "best"! The gap is big!

Wen Ruohuai said very happily: "Ms. Xu rejected my money and is willing to become friends with me regardless of money interests! He saw my sincerity."

Han Honghu took a cold breath and nodded seriously. He had never seen Wen Ruo hold such an attitude before. Even when facing a large client, he always responded calmly and unsmiling.

Even if he is going to meet everyone in the painting circle that he likes very much, he should be holding it, and he has to hold it.

He once ridiculed Han Honghu. Those bosses who are inferior when seeing everyone in the painting circle are really disgusting.

But now he has lived like that, even worse.

Wen Ruohuai looked at Han Honghu and asked with a smile: "Do you think I have changed?"

How dare Han Honghu nod his head, he can only say: "It's Teacher Xu that is so amazing!"

Wen Ruohuai nodded: "Yeah"

He came to Xu Cong's house during this trip and he was very satisfied!

Not only did I get a landscape painting calligraphy that exceeded my expectations, but I also had a relatively interesting "Tai Chi-style conversation" with Xu Cong.

After expressing his position, he became familiar with Xu Cong.

"This trip is worthwhile!"

Wen Ruohuai looked back at the direction of Xu Cong's house, eyes full of respect.

After Xu Cong left the car, he also went back to the house. Lin Mengjiao was shrinking under the covers at this time, but his eyes widened.

"Who's here?"

Xu Cong said casually: "Boss Han and his boss."

Lin Mengjiao's expression suddenly exaggerated: "!!!"

"What are they doing here?"

Xu Cong said to her jokingly: "Give me money, do you believe it?"

Lin Mengjiao said admiringly: "I believe it! I believe everything you say!"

Xu Cong rolled his eyes and said contemptuously: "But before, some people didn't say that, saying that I was a big liar!"

Grin!

Lin Mengjiao blushed.

"Xu Cong! You stinky durian mang!"

"I was wrong! Xu Cong! I was wrong! Dad! Dad, I was wrong..."

This weekend is really meaningful. Although there is less learning in the true sense, there is still a lot of learning in other areas.

"No way, no way! I'm going to get up to study! I'm going to school tomorrow morning!"

At noon, Lin Mengjiao got up to put on clothes and just walked out of the room.

"Bang Dang!!!"

"Boom boom boom!"

"Open the door! In broad daylight, what door do you plug in at home?"

It was Zhou Xiuyun and Xu Junshan who came back from the tour.

Lin Mengjiao was almost scared to death.

"!!!"

"Auntie, uncle, you are back!"

She was guilty and didn't dare to look into their eyes and open the door. Zhou Xiuyun and Xu Junshan were very happy.

"Where's Xu Cong? Haven't gotten up yet? This guy, how about lying in bed?"

"Jiaojiao, you can't be so used to him!"

Lin Mengjiao quickly explained and said to them: "Get up! Xu Cong gets up!"

After Xu Junshan came in, looking at the tobacco, alcohol and some gifts in the room, he was confused.

"Moutai? Where did this come from! Son! What is going on?"

"So much wine! Did you go to grab someone's Moutai shop?"

"Hiss! Cellar! Decades of cellar! This will cost thousands, maybe even tens of thousands of bottles."

As soon as these words came out, Zhou Xiuyun and Lin Mengjiao were stunned, and Lin Mengjiao said bluntly: "Is this wine so expensive? Didn't the Han boss say that he bought rice paper as a gift?"

Xu Junshan looked at her like an idiot: "Do you think it is possible???"

"Buy rice paper? Buying rice paper with gold will not give you wine like this!"

"Jiaojiao, what is going on?"

Lin Mengjiao recounted Xu Cong's painting for Wen Ruohuai.

Zhou Xiuyun: "Hi..."

Xu Junshan: "His..."

At this time, Xu Cong came out of the room and saw the dumbfounded expressions of the two of them. He couldn't help asking: "Parents? Parents? Parents! Why are you all stunned?"

brush!

The two men suddenly looked at Xu Cong, their eyes filled with shock.

"Xu Cong! Are these from the Han boss?" Dad Xu Junshan said in shock.

Xu Cong looked at the gifts and said calmly, "Are you not used to it yet?"

Zhou Xiuyun and Xu Junshan opened their mouths and closed again, not knowing what to say for a while.

Xu Junshan's gaze wandered between the wine and Xu Cong. In the end, he paid special attention to these wines and put his eyes on the wine thoroughly.

Zhou Xiuyun squatted down, picked up a bottle, looked carefully at Xu Cong and said to Xu Cong: "This is Moutai? Real Moutai? How many thousand yuan a bottle?"

Xu Cong nodded, smiled and said, "Almost."

Xu Junshan said at this time: "The price may be higher!"

Zhou Xiuyun immediately turned her head to look at him: "!!!"

Lin Mengjiao couldn't help taking a breath, and asked him, "Are these wines so expensive?"

Looking at Xu Cong, she couldn't help but glared, and said a little, "Why didn't you say it earlier!"

"I'm so embarrassed! I also said, how much rice paper do I need to buy in order to give so much wine..."

And this sentence was still spoken in front of others, Lin Mengjiao wanted to find a mouse hole to get in!

Xu Cong chuckled twice, and didn't worry too much about this issue, and said to Lin Mengjiao: "Since you are back, we won't be able to eat! Let's go and study."

When the words were over, he took Lin Mengjiao back to the room and handed it over to Zhou Xiuyun and Xu Junshan.

After Lin Mengjiao was dragged into the room by him, she looked at him stupidly and asked, "What are you doing???"

Xu Cong chuckled and said: "They go home happily, just let them work, we are relaxed and relaxed."

Lin Mengjiao nodded and smirked, then she turned on the computer, started looking for questions, and replied.

...

Brush! Brush!

Brush! Brush!

Xu Cong watched her do the questions and supervised the quality of the questions. Suddenly Xu Cong finally saw a better question, so he immediately asked Lin Mengjiao to stop.

"Stop, just do this question."

The diving bell is a kind of underwater life-saving equipment. It is a container with an open bottom and a closed upper part, and its appearance is similar to that of a bell.

When the diving bell is underwater, there is air in the space above its interior to meet the needs of divers for underwater avoidance.

For the convenience of calculation, the diving bell is simplified as a cylinder with a cross-sectional area of ​​S, a height of h, and a downward opening; the working mother ship hoists the diving bell from an opening above the water surface to a depth of H, as shown in the figure. .

It is known that the density of water is ρ, the magnitude of gravitational acceleration is g, and the atmospheric pressure is p0, Hh, ignoring changes in temperature and changes in water density with depth.

(1) Find the height l of the water entering the cylinder;

(2) Keep H unchanged, press in the air to discharge all the water in the cylinder, and find the volume of the pressed air when its pressure is p0.
