Waking up in the morning and smiling at the sky, after smiling I go back to sleep,
After waking up I smile at the sky again, then sleep for a bit longer.
When I get up in the morning, feeling refreshed all over,
I know I’ve overslept again.
Life is…
Those nights when I want to sleep ten minutes longer,
Those mornings when I want to sleep five minutes longer.
When I open my eyes I want to sleep, while washing up I want to sleep,
While eating I want to sleep, when going out I want to sleep,
While walking I want to sleep, on the bus I want to sleep,
While working I want to sleep, while slacking off I want to sleep,
Standing I want to sleep, sitting I want to sleep,
Lying down I want to sleep, playing on my phone I want to sleep,
Chatting I want to sleep…
When I finally lie down in bed, I start to struggle:
I want to sleep, but I don’t want to give it up.
People who can jump up when the alarm goes off are like a piece of toast,
Some are like a bottle of wine that takes fifteen minutes to wake up,
And I am like a fried egg, rolling over to continue sleeping,
Sometimes I’m like a soup dumpling, holding my pee and refusing to get up.
I told Teacher Wu that I was sleepy and wanted to sleep,
And he went around saying I was unwanted…
Teacher Wu’s little life class:
The most magical Chinese character is “觉”,
It represents two completely opposite meanings,
One is pronounced jué, and the other jiào,
They are antonyms of each other,
You can make your choice.
Teacher Wu quietly told me:
If you want to flip over quickly…
You must sleep on your side!
As expected from Tsinghua, very reasonable advice.
At night, sleep well,
In dreams, you will find what you want.
During the day, study hard,
There are things you don’t know in the videos—

I like staying up late because:
The world between one and five in the morning is quiet,
No one has any demands of me,
Even staring at the wall for four hours is fine,
I love silence and tranquility, I love it.
The downsides of staying up late: hormonal imbalance, hair loss,
Oily skin, delayed reactions,
Worsening memory, lowered immunity,
Severe dark circles, excessive liver fire and declining vision…
The benefits of staying up late: refreshing!
Every night I tell myself that staying up late will kill me,
It turns out, I really don’t fear death.
Come on, let’s stay up late, anyway I have plenty of hair,
I, who am poor, live a life of stealing sleep and missing sleep.
Teacher Wu reminds me that staying up late reduces lifespan,
But the part of my lifespan that is reduced by staying up late,
Isn’t it just being compensated by the nights I stay up now?
And the lifespan I’m reducing is the old age lifespan,
What I’m staying up for now is the youth night,
So, I’m using my young body,
To enjoy the lifespan of old age in advance, it’s worth it.
No one can save me, I know.
I look at the distant mountains, desolate and compassionate,
I look at the lights, dim and lonely,
I look at the crowd, lively and crowded,
Perhaps there is no place for me in this world.
I exhaust all my strength,
But I can’t break the prison in my heart.
The heaviness of past days,
Like a thousand-pound boulder, pressing on my heart,
It bleeds day and night,
Wailing and lamenting.
No one can save me, unless…
Teacher Wu’s wonderful little movie!
Scan the QR code or click the bottom left corner “Read the original text”:
The limitations of fate may always exist,
But the unyielding challenges are indispensable.
When the alarm goes off in the morning, I have to get up,
Forced to work, starting a new day,
I feel like a slave to the alarm clock.
When I get to the company, I start to get busy,
I have to wash my cup, choose the tea for today,
Wipe the desk, charge my phone,
Turn on the computer, then go get water,
Check today’s work content,
Browse the work group, and then I’m tired…
Since I’m here, I’ll just relax for a bit.
When I was young, I hated Zhu Bajie,
Lazy, irresponsible, and not united,
After working, I found out that I am Zhu Bajie,
And I was caught sleeping on the desk by my boss…
Let me share a hot knowledge:
After saying “I’m sorry”, add “Is that okay”,
It can reignite the fire that was calmed down.
Water has its source, trees have their roots,
Not wanting to go to work has its reasons.
If the boss bullies me, I will let him know:
What a true coward is!
When he is not paying attention, I glared at him fiercely.
The phrase “forgive and forget” is too hypocritical,
My life motto is: Don’t let me have the chance.
Once I finish Teacher Wu’s STM32 tutorial,
I’ll slam my resignation letter on the boss’s desk,
I’ve long thought about the reason for resignation:
Embedded salaries are so high, I want to give it a try.
