After two years of marriage, the officer husband can’t stand it any longer.

Lu Changqing, who was alone in the empty room, stared at the darkness outside the window. The night sky was quite beautiful, because there were no heavy industrial developments and there were more stars.

He was rubbing the safety watch in his hand. Is everyone okay?

I looked at my watch again and saw that it was already past midnight. He closed his eyes tightly and tried hard to fall asleep, but thoughts kept flooding into his mind, making it difficult to calm down.

He thought of that home full of joy again...

!!!

Early morning~

Lu Changqing just got up and was taken to the planting base. The goods in front were very good and the buyers were very satisfied.

When they came back, they saw Qian Yufei and Chai Bo. Lu Changqing restrained himself from thinking about it, just pretending that Jiang Waner was dead and the person in front of him was Qian Yufei...

"Xigu, are you married?" Yi Xiaoliu brought up the topic.

"I've talked to a few friends, but I'm not married yet. In our line of work, my family is a burden." He replied, but he still felt sour in his heart.

Yi Xiaoliu patted him on the shoulder: "Don't get married. Once you get married, you won't be free. If you don't get married, you can do whatever you want."

"Alas!" Lu Changqing sighed: "It's good to be alone, it's good..."

Let go of the past and start from the beginning. Jiang Waner doesn't like him anyway, it's just wishful thinking and unrequited love.

There will be other people breaking into his life in the future. As long as Hawkeye is caught, everyone will be happy.

Bei City University~Opening day!

Gu Beinian put the calendar on her desk and marked numbers 1 to 3 with a pen. She had prepared lessons yesterday. Today's first lesson was electrodynamics. She had a headache, and so did the students!

If I had known earlier, I should have become a Chinese teacher, or teaching English would be good. At least it would not require much mental effort. What kind of physics and chemistry should I teach?

It's all Professor Han's fault for instigating her and seriously brainwashing her.

She glanced at the students in the classroom and started to call their names. She didn't expect that there were still students who hadn't come today, so don't blame her for marking their names.

She asked the students to open their textbooks and start explaining today's lesson.

"Students, today we are going to learn the first knowledge point in electrodynamics - electric field and magnetic field. In this process, we will learn the concepts, properties and mutual relations of electric field and magnetic field, as well as their role in electromagnetism. Application." Her voice was clear and firm, making the students feel at ease and at ease.

Through simple explanations and lively and interesting demonstrations, she helped students understand the concepts and properties of electric and magnetic fields, and guided them to conduct some simple experiments and calculations.

Most of the students gradually entered the state, and there were a few who fell asleep. She had become accustomed to it and was not surprised.

When the final exam comes, I burn incense, worship Buddha and pray, and all the great gods show their magical powers, and I can see all kinds of pictures.

The next class went to the Chemistry Department, and they had to change to the teaching building next to it before class started. A student pointed at Gu Beinian with a selfie stick.

"Classmate, can you please stop making fun of me? My pores have been exposed by you." Her words suddenly caused the students in the audience to laugh.

"It's okay, teacher, your skin is so good, you can't even tell."

"Yes, please share with me what brand of skin care products you use."

"Teacher, please give me an example. I'm recording a video."

Gu Beinian looked at them. He was really convinced by these students. What else could he do? Just tell me!

“Skin care products are one of the common products that use chemical principles to achieve their effects.”

As a teacher, Gu Beinian is well aware of this, so when she explains knowledge, she often cites examples of skin care products to better understand chemical principles.

"For example, alcohol compounds, ethanol is one of the common alcohol compounds, which can be used in cosmetics as solvents and moisturizers. The molecular formula of ethanol is C2H5OH, and the hydroxyl group (-OH) is a hydrophilic The sex group can help cosmetics absorb water better, thereby keeping the skin hydrated."

"Such as vitamin C, arbutin, hyaluronic acid, etc. These ingredients can help the skin retain moisture, resist oxidation, and fade spots."

“Vitamin C can inhibit the activity of tyrosinase, thereby reducing the synthesis of melanin; arbutin can inhibit the precipitation of melanin, thereby fading spots; hyaluronic acid can increase the moisture content of the skin, thereby improving the elasticity and luster of the skin. "

"Finally, there are antioxidant ingredients. Antioxidant ingredients can help the skin resist the damage of free radicals, thereby achieving the effect of protecting the skin. For example, vitamin E, tea polyphenols, anthocyanins, etc., these ingredients can help the skin resist the damage of free radicals. , thereby reducing the rate of skin aging and oxidation.”

By explaining the chemical ingredients in skin care products, students not only better understand the chemical principles, but also realize the importance of skin care products for skin health.

"In short, skin care products are not a panacea, but using them correctly can help you better protect your skin and delay skin aging."

"When choosing skin care products, you need to pay attention to the safety and effectiveness of the ingredients. Different skin types and needs require different ingredients to achieve the best results. Don't pursue blindly."

A classmate asked: "Teacher, do you know? I always find it interesting that you use alcohol compounds as examples."

"How do you say that?" Gu Beinian asked back.

The student thought for a few seconds and then said: "Because alcohol compounds are compounds containing hydroxyl groups, and hydroxyl group is a hydrophilic group, alcohol compounds can be used as moisturizers and solvents in cosmetics, so we can Understand why alcohol compounds help cosmetics be better absorbed into the skin."

Gu Beinian smiled lightly: "Not bad!"

As the bell rang, the students relaxed. She didn't like to drag the class, so she ended the get out of class immediately.

Back in the office, Gu Beinian leaned back on his chair and rubbed his sore lower back: "I'm so exhausted~"

"Is it so hard for a university teacher?" the new male intern teacher next to her joked.

Gu Beinian didn't look up, packed up the lesson plan and replied: "Squeeze it layer by layer!"

She picked up her phone and found that the physics group was exploding. She quickly scrolled through the chat history. Oh, there was a classmate who defeated other classmates with a question. She was looking through the students' discussion in the group when a call came in on her phone. , the note is displayed as Professor Han.

Gu Beinian answered the phone and Professor Han's voice came: "Xiao Nian, do you have time recently?"

Whenever Professor Han asked this question, Gu Beinian trembled a little, something was going to happen again!

She almost blurted out: "No."

Professor Han smiled and said, "The time and information address have been sent to your mobile phone. I'm still busy. That's it for now. Bye!"

"..."

"Eh eh eh..."

After hanging up the phone, Gu Beinian rubbed his brows helplessly. This old man always does this. Don't think that she won't get angry. I, Gu Beinian, also have a temper!

She clicked on her phone and looked at what kind of lecture it was...
