In class, at a glance, most of the class is full of boys, and there are only a few girls. A young female teacher in a navy blue suit is holding a pair of large triangular teaching aids and demonstrating on the blackboard how to draw 45-degree diagonal lines at equal intervals. Although it is a professional attire, the female teacher pays great attention to detail with a crystal brooch on the bow of the white shirt, and the shoulder-length curls are matched with a crystal butterfly with Korean braided hair, which echoes the crystal brooch. The female teacher reminded the students while drawing lines: "Please remember that the cross-sectional symbols for metallic materials in the cross-sectional view should be expressed in a thin solid line that is inclined 45 degrees horizontally and spaced equally, and please draw it with an H or HB pencil on the drawing." "This is a mechanical drawing course, although there can be PPT to assist teaching, but the actual drawing method also needs to be demonstrated by the teacher, students learn manual drawing, before they can start to teach computer-aided drawing, which is often called Auto CAD teaching. Zhao Anran is a mechanical teacher in this J secondary school, and undertakes courses such as "Mechanical Drawing", "Auto CAD" and "Mechanical Basics".

"Next is the students' practice time, please open the workbook, do the cross-sectional view exercises, students who don't understand can raise their hands and ask me", Zhao Anran said as he opened the workbook, and then glanced at the podium, "Yang Peishu, have you started to meet with Zhou again?" The boy in the last row was sleeping on the table, and he was named by Zhao Anran and quickly looked up, but then replied very jokingly: "Teacher Zhao, I'm not Yang Peishu, I'm Yang Peiji, you recognize the wrong person." "There is a pair of twin brothers in this class, Zhao Anran has noticed it on the first day of class, in order not to mistake the students, she specially paid attention to the differences in the details of the twins, Yang Peishu has a small ear stud on his left ear, but Yang Peiji did not. Zhao Anran knew that this was a student deliberately finding fault, she smiled and walked off the podium, walked up to the boy elegantly, and then gently pinched his ear, "These metal studs are good, are you going to take the punk route?" How courageous the pierced boy is! Does it hurt? Why don't you share your experience with ear piercing? Yang Peishu. The students burst into laughter, and Yang Peishu thought to himself, this young teacher is so sharp, it turns out that he has already seen through himself, so forget it and don't tease her.

The bell rang after class, Zhao Anran returned to the teaching and research room with a bunch of teaching aids, her navy blue coat was stained with some white chalk ash, she washed her hands first, and then patted her uniform with a wet towel, and the first thing she did when she returned to her seat was to kick off the pair of 10 cm black high heels, "Finally relieved!" Zhao Anran took a deep breath. I thought to myself: height is really my hard injury! Less than 160 cm is a little man, and you have to wear any clothes with high heels to have an aura, my poor soles of my feet......

J school is the city's key secondary school, mechanical major is also the school's key major, Zhao Anran into this school is also after three rounds of theoretical, practical and trial lectures, won the first place, only to get a formal establishment of the teacher's position. When she first entered the school, the old teachers couldn't believe that such a petite young teacher with a beautiful face and fashionable dress could operate the semi-automatic lathe used for teaching in the school so skillfully, and the contrast was too great!

Zhao Anran is indeed a rule-breaking existence, thanks to the good genes of her parents, she has been a beauty since she was a child, with a pair of big eyes on her slap face, double eyelids and lying silkworms make her more charming when she laughs; The bridge of her nose is not only straight but also very high, and people always ask her if she has padded the bridge of her nose, and she has to emphasize that she is the original every time; With just the right thickness of the lips and obvious lip peaks and slightly upturned corners of the mouth, if you wear a positive red lipstick, it is definitely a stunner. But she never regarded herself as a beauty, she wanted to be a talented girl, she had excellent grades in Chinese and English in high school, and her liberal arts grades were not bad, but she had to choose science, although her math grades were not ideal, but she loved to study physics, so she should have studied an engineering major in college. The college stage is the peak of her appearance, Zhao Anran, who can sing and dance and is sociable, is still the vice president of the student union, and is the goddess in the hearts of many boys, although she has many suitors, but she politely refused, because the goddess also has a male god in her heart.

Zhao Anran's male god is her high school classmate Liu Hanlin, his academic performance has always been better than Zhao Anran, but he is low-key. Liu Hanlin wanted to be admitted to 985 University, and his whole mind was on studying, and when other boys played football and basketball, he was reading and studying. Liu Hanlin, who has always been a weak scholar in high school, has fair skin, single eyelids and a high nose bridge, but he is not particularly conspicuous among the boys in the same class. Zhao Anran doesn't know why she admires this type of boy, every time after the exam, she will secretly calculate how many points she still has to catch up with the male god, and this "chase" is just a chase on the score, and there is no intention of chasing the male god as her boyfriend. After the college entrance examination, Zhao Anran and Liu Hanlin were admitted to universities in different cities, but they have always kept in touch, and when they return to their hometown during the holidays, they will meet their classmates to catch up with the old days. The year they graduated from college, they made an appointment to take the postgraduate entrance examination, and Liu Hanlin was admitted to a master's degree in an ordinary university that he didn't like very much, but Zhao Anran fell off the list. With Zhao Anran's arrogant and stubborn character, she vowed not to give up until she achieved her goal, so the next year she was admitted to a master's degree in 211 colleges and universities in the same city as Liu Hanlin. In this way, Liu Hanlin and Zhao Anran continued to keep in touch and occasionally had a meal.

"Me and my last stubbornness, clench your hands and never ......let go" Zhao Anran's mobile phone rang, she has always liked the Mayday Orchestra, and this song "Stubbornness" is even more in line with her character, so it is set to a mobile phone ringtone. It was Liu Hanlin who called, "Zhao Anran, look at our school website, the doctoral enrollment brochure has come out, don't you want to take the doctoral exam?" "Oh, I just got out of class, I'll turn on the computer now, thank you Brother Lin!" Zhao Anran pretended to be relaxed, in order to hide his recent embarrassment. Oh, yes! Zhao Anran, who has always been proud, wanted to continue to study for a doctorate after graduating with a master's degree, because Liu Hanlin, who she has always regarded as a goal, has been admitted to a 985 university for a doctoral degree, but Zhao Anran's mother is resolutely opposed, on the grounds that no one dares to ask for a girl to get a doctorate, and how can she have an advantage in the marriage and love market when she is older? These reasons directly made Zhao Anran roll her eyes, but from her grandmother to the seven aunts and eight aunts, they all persuaded her with full firepower to take into account her mother's feelings, Zhao Anran's father was no longer there, and her mother only had Zhao Anran to rely on. In the end, Zhao Anran compromised, she could only work first, then go on a blind date, and then choose a suitable person to marry and have children. The so-called transition from girl to woman should be completed step by step before the age of 30. After graduating with a doctorate, Liu Hanlin became a teacher at S University in Ming City, not far from his hometown. A month ago, Zhao Anran sent a WeChat message to Liu Hanlin, saying that he was going to take the doctoral exam and asked him to help pay attention, so he really helped her pay attention. And didn't ask her why the child was in a hurry to take the exam before he was a year old.
