27-year-old domineering CEO falls in love with 45-year-old cleaning lady?

Domestic short dramas are crazy!

The boss asked me to write something according to this style.

Part One:

The female CEO falls in love with me, who has no money or house and spends all day typing.

“I want to take everything that doesn’t belong to me!”

The boss said I look ugly and want to be beautiful…

Part Two:

The CEO calls his wife whom he has never met,

and the girl next to him suddenly receives a call!

The boss said I am acting like Hitchcock…

Part Three:

The little match girl is too cold,

and she struck her last match.

Suddenly, a CEO appeared in the flame,

he smiled wickedly and said to the little girl:

“Woman, you are playing with fire!”

The boss said I am a pervert…

Part Four:

As smart as I am, I decisively choose to copy homework!

25-year-old CEO falls in love with me, who has been dead for 120 years.

Just because he glanced at my life on the tombstone,

the CEO, unwilling to forget, spent trillions,

using alien technology to extract DNA to clone me.

Then, the CEO froze himself,

waiting for me to enroll in college,

when the CEO would unfreeze and crazily pursue me.

The boss asked me: “Do you think this plot is reasonable?”

I don’t know what the CEO is like when he goes crazy…

The last time a woman pursued me, I didn’t pay for my buns.

Network knowledge storm absorption! Output——

Part Five:

“I gave my ex-girlfriend a million,

because she betrayed me,

then another woman betrayed me,

I handed over another million,

Every woman who betrays me gets a million,

but loyal women are worth billions.”

The boss sighed for some reason…

Teacher Lei Yu said, help me find the feeling of the CEO.

“Have you watched my new video?”

“Not yet.”

“Hurry up and watch, this is an order!Release of the MQTT Video Tutorial by Shang Silicon Valley

The first technological revolution liberated manpower in the steam age; the second technological revolution realized the mutual conversion of mechanical energy and electrical energy, further iterating power technology; the third technological revolution, with computers and the internet, greatly promoted the transformation of human society, and the Internet of Things rapidly emerged alongside this technological revolution.

MQTT, benefiting from its simplicity, lightweight efficiency, massive link support, secure bi-directional communication, and multi-platform support, has become the communication protocol of choice in the IoT industry.

This tutorial is meticulously developed by Shang Silicon Valley Research Institute and is a significant release! The content of the tutorial is comprehensive, covering the MQTT protocol architecture and working principles, session persistence, retained messages, will messages, security mechanisms, QoS levels, and many other aspects, combining theory with practice, covering every detail of the MQTT protocol, and using real cases of smart light bulbs to help learners understand the best practices of MQTT in the IoT industry.

The tutorial is step-by-step, starting from scratch, gradually guiding learners to master the basic operations of MQTT, the basic usage of EMQX Dashboard, and MQTT client programming. At the same time, the tutorial balances depth and breadth, providing an in-depth analysis of the internal mechanisms of the MQTT protocol, detailing the security mechanisms of MQTT, including authentication, authorization, blacklists, and connection jitter checks, enabling learners to build highly secure MQTT systems!

These days, short dramas are all about domineering CEOs falling in love with me,

showing off wealth, dog blood, twists, Mary Sue, revenge…

Famous works would have to be renamed if published now:

“Thunderstorm” – “Rich Young Master Falls in Love with Glamorous Stepmom”

“Dream of the Red Chamber” – “Sick Beauty Returns to the Rich Family”

“Camel Xiangzi” – “Domineering Girl Forces Love”

“Journey to the West” – “Female CEO Wants to Conquer My Master”

“That night, you hurt me.”

Flower shadows move, red curtains sway in the wind,

with a phoenix crown and gorgeous dress, she is stunningly beautiful,

the queen calls out to her brother, making Tang Seng’s heart tremble,

if it weren’t for the scorpion spirit coming at this moment…

Tang Seng must passion up!

Looking at her with tearful eyes, he shouts:

“To hell with the emptiness of the four realms, my lady, I’m coming!”

Willing to abandon my cassock, give up my Buddhist teachings,

spend my ten lifetimes of cultivation, just to be with you at the ends of the earth,

small thatched fence, black hair turns white.

Does Sun Wukong want to stop? Old Tang just chants the spell.

Fun fact: The tight-sealing spell that Tang Seng chanted back then,

translated into Chinese, is actually not that complicated,

let alone Sun Wukong, anyone who hears this spell will get a headache:

“Education, housing, healthcare, and elderly care,

Education, housing, healthcare, and elderly care,

Education, housing, healthcare, and elderly care…”

Dating is not as interesting as doing technology!

Watch fewer brainless short dramas, learn more useful knowledge.

73-year-old Zhang Jizhong is busy being a dad,

74-year-old Liu Xiaoqing is busy dating,

why are you in such a hurry to find a partner?

Growth is the hard truth, starting the journey ofbreaking the spell!

The essence of the CEO, Mr. Jin Yong understands best.

Take a look at Zhang Wuji’s taste in women:

In his first love, he liked the beautiful Zhu Jiuzhen,

when hurt, he appreciated the care of Yin Li,

in times of crisis, he admired the companionship of Xiao Zhao,

now with some success, he recalls an old acquaintance,

the now noble lady Zhou Zhiruo,

as the big boss, he likes the beautiful enemy Zhao Min.

When young, he liked pretty girls based on looks,

as he grew up, he liked girls who treated him well,

as he matured, he liked obedient neighbor girls,

when he had status, he liked beautiful girls from good families,

and as a big shot, he likes stimulating female CEOs.

“Hmph, men…”

Feel the control of the CEO’s daughter over the silly boy:

“Jing Ge, after I die, there are three permissions and three prohibitions.

I allow you to marry Huazheng, but you are not allowed to marry other women,

because Huazheng is truly good to you,

If you marry another woman, I’m afraid she will deceive you.

I allow you to set up a grave to worship me,

but you are not allowed to bring Huazheng to worship me together,

because I will always be petty!

After I die, I allow you to be sad for a while,

but you are not allowed to be depressed.”

This little nagging, which man can withstand?

You can learn something from reading martial arts novels.

In the past, we read books, watched brainy movies,

played some large and complex games,

now we lie in bed watching short videos, watching short dramas,

and even find it too lazy to calculate discounts on Double Eleven.

Your attention span is getting harder to maintain for long periods,

we no longer read books, but look at summaries of quotes from a book,

we don’t watch movies, but watch explanations of a movie,

we don’t watch TV shows, as they take too long,

short dramas can satisfy us in minutes.

In psychology, this is called the sunflower seed effect,

while eating sunflower seeds, each small positive feedback,

small investment, continuous deliciousness,

you find you can’t stop.

When watching short videos, one after another,

watch a bit, feel good, watch a bit, feel good,

and before you know it, two or three hours have passed…

In this fragmented era,

it’s hard to focus on one thing for long,

there are too many things that can distract you.

Some people lose because they can’t persist,

some lose because they can’t start.

Persisting in doing things that require long-term investment,

like spending one or two hours learning every day,

in this restless world, be a clear-headed person!

“I am Tang Seng,

coming from the East Land of Tang,

heading west to worship Buddha and seek scriptures.”

Who am I, where did I come from, where am I going?

Stay true to yourself, work hard, and just do it!

“If I don’t reach Tianzhu, I won’t return to the East.”
