The sun sets in the west, and though one is not old, seize the time to run around.
Don’t wait until your legs are not good, and you need someone to help you walk.
I want to go out with my girlfriend for a few days during the National Day holiday.
Does anyone have a good girlfriend to recommend?
A person who always wants to travel,
indicates that he is not happy.
And a person who always wants to travel but hasn’t gone,
means he is both poor and unhappy.
This sentence hurt me, but I laughed it off.
Scientists have found:
Children who often go out to see the world,
have a much higher chance of success than others.
Why are children who travel frequently more successful as adults?
After extensive research, scientists concluded:
Because their families are usually quite wealthy.
Wealthy people who are scolded by their bosses can quit their jobs and travel around;
If I get scolded by my boss,
I can only angrily blow off steam.
Actually, traveling is not that interesting,
except for different place names, there’s not much difference.
Every tourist city has five common things:
A pedestrian street specifically for ripping off foreign tourists,
An old street selling handmade products,
A dirty old town with mixed quality,
A new district with many tall buildings but few people,
A historic town or alley that makes you want to die,
where the food is all the same,
and everywhere you see “I miss you here.”
If it feels like everywhere in the country is the same, congratulations,
you are entering the second stage of traveling!
Go hiking, climb snow mountains, dive, explore uninhabited areas…
Try all the new things you’ve never tried before,
and indulge in the beauty you’ve never seen before.
As for me, I’ve already reached the final stage:
Lying in bed watching you travel.
Wishing you a hard-earned holiday,
which results in skyrocketing ticket and hotel prices,
and the worst travel experience!
I am the villain; as long as I stay home,
no traveler is innocent.
I have sunk into evil… 
Here he comes, Liu Bo is coming towards us with gifts!
I thought he would slap five million in my hands,
making my dark heart dissipate instantly,
and transform into a sunny youth who travels the world.
Unexpectedly, he pulled out a set of videos,
The seven-day National Day holiday is the perfect time to learn:
Shang Silicon Valley 51 Microcontroller Video Tutorial
Direct link to Bilibili：
https://www.bilibili.com/video/BV139sSe7E2K
The 51 microcontroller, with its simple architecture and mature ecosystem, is an ideal choice for beginners in embedded development. By learning the 51 microcontroller, you can easily grasp the core concepts of microcontrollers, understand the basic principles of embedded systems, and become familiar with the way hardware and software work together, laying a solid foundation for further learning!
This tutorial covers the major core modules of the 51 microcontroller: general input/output ports, interrupt systems, timers, serial communication, etc. These concepts are universal in more advanced microcontrollers like STM32, so after finishing the 51 microcontroller, you will be able to get started with these more complex microcontrollers much faster.
The tutorial adopts a case-based teaching approach, driving explanations through cases such as digital tubes, LED dot matrix, buttons, buzzers, and OLED screens, with code written line by line. By combining theory with practice through cases, beginners can gain a deeper understanding of the core concepts in microcontrollers. It still follows Shang Silicon Valley’s consistent style: detailed explanations and generous gifts. In addition to the videos, accompanying materials: code, notes, and software, are all included, providing a one-stop service that takes everything away, making learning worry-free!

Chinese-style travel:
Get on the bus and sleep, get off the bus to pee,
Arrive at the scenic spot and take a photo,
When asked later, know nothing.
For many people, traveling is just a photography contest on social media.
I used to not understand why Li Bai wrote poems wherever he went,
Until I went out to play myself and
posted dozens of updates in a day…
I can’t lose this competition!
Everyone talks about traveling to Dubai, Abu Dhabi, etc.,
Tell me the detailed travel expenses and strategies,
After the National Day holiday, I will go back to work,
and I need to boast to my colleagues, thank you.
As vain as I am, I must show off my value!
Someone asked a traveler:
You have been to many places, where do you think is the best?
He said, of course, home.
If home is good, why travel?
He replied, how would I know home is good if I don’t go out?
Many people mistakenly think that liking to travel, loving food,
and participating in various entertainment means loving life.
Staying at home, reading, playing on the phone, sleeping in…
does not mean not loving life.
In fact, life has many different appearances,
loving life is a mindset,
not a way of loving life.
If you are like me and stay at home,
start learning today, complete this tutorial during the holiday,
as excellent as you are, the long holiday is also meaningful.
National Day holiday fun, leveling up is even happier!
Scan the code or click the bottom left corner “Read the original text“:
Traveling the green mountains, one remains youthful, the scenery here is uniquely good.
Many things are like traveling, such as learning,
when you decide to set off,
the most difficult part is already completed.
When tired from studying during the holiday, in your own city,
just take a subway or bus,
pick a station you wouldn’t usually get off at,
get off and take a random walk,
in unfamiliar streets, see unfamiliar stores,
stumble upon a small park, sit down and daydream,
it all has an excellent healing effect, proven effective.
Living is traveling.
I go from one day to another,
just like going from one station to another,
riding the train of my body or fate,
sticking my head out the window,
looking at the streets, looking at the squares,
looking at people’s faces and postures,
these are always the same,yet always different,
like scenery.
—— Pessoa, “The Book of Disquiet”
You can also go hiking and pray in the suburbs.
In the past, whenever I went out, no matter which temple I passed,
I had to go in and worship all the gods.
My boss asked me, what’s the use of doing this?
I said you don’t understand, this is called probability theory,
the more I worship, the more likely one will take care of me!
The boss splashed a bucket of cold water on me:
Have you never worked anywhere?
If everyone is responsible for one thing,
then no one is responsible for it.
Ah, this…
As expected of a boss, always so annoying.
Why do we like to travel?
Just like a package in transit,
just like buying a good concert ticket,
it’s all about creating expectations in a mundane life,
it’s the motivation for people to endure long periods of desolation.
Traveling is an escape from mundane life.
In unfamiliar cities, we become braver and more confident,
in places where we know no one,
we live more sincerely,
because no one knows us, we can be a brand new self,
which means we can walk sideways on the road,
the whole world is mine,
I don’t belong here,
so whatever I do will leave no trace.
Why do we have to take pictures?
You may not understand photography, but you must record.
Many things cannot be remembered later,
the meaning of a photo is to turn a moment into eternity,
when you look back, remembering the feelings at that time,
photos make memories more concrete and vivid.
What reason do we have not to record life well?
However, taking pictures of a girlfriend is indeed difficult,
without two skills, you might die young.
Some girls say:
There are two things in this world that cannot be looked at directly,
one is the sun, and the other is the photos taken by their boyfriends.
“Can you take candid shots?”
“Can you compose well?”
“Can you guide me?”
What’s even scarier is, if you say you can do all of that,
she will definitely ask you how you learned it.
Brothers, maybe it’s better to stay home and study…
Working on relationships is not as interesting as working on technology!
