I don’t think this question is available unless it is “ why can’t people just stop lying?”.

"Available" isn't the proper usage here; maybe you meant 'appropriate'?

As human beings, I guess you know we all need to lie in ourwe all lie every single day, even if we don’t want to do it.

you can remove the "I guess you know" part. It's not incorrect, it just makes the sentence read weirdly.

We always lie to someonpeople for variableous reasons.

Sometimes we lie to protect ourselves because we have to accept our powerlessness.

There are so many situations in which people lie to others.

This isn't a complete sentence; I added a suggested phrase to make it complete

Anyway, wWe cannot live normally without lying.

First, I will let you knowtell you why we lie to protect ourselves.

Now I am currently working at a top internet company in China, which is responsible for game product anding games. I have a damn shitty leader who always pushes me.

He often tells me I should do something good, but he never tells me thehis standard ofor the works, even the ddl also.

don't know what DDL is referring to here, so I didn't edit it.

Moreover, he doesn’t allow me to leave after work time，“ wI've finished work. "We only can leave after 9.00 pmPM every day unless you request leave.” This is what he said when I tried to leave at 6.00 pm.

I feel damn and fullwas upset and angry, so I decided to leave without informing him.

This is talking about an action that happened in the past, so you need to use the past tense form of the verb.

After that, he asked me where I am.

I responded to him:” "I am going to the hospital andbecause I am sick.” Every time he asked me why I am not at the working sitoffice after 6.00 pm, I responded with that.

Finally, he never asked me that again,. This is an example of how lies can protect us.

The Another example is how lying can help us to protect others.

I am 21, and I am studying thetaking university courses online because of the covid-19 epidemic.

So I have time to go to other places not at home to do my internship.

I have experienced one and a half years ofor working experience, even though I only have two years of online university life onlinexperience.

I am keeping doing multiple tasks whichto make money, ands well as studying hard.

don't forget to add -ing to present tense verbs

I have got two times dean’s list and gotten on the den's list two times, and have also gotten into big companies as an intern, but e. Every time I reply to my dadmy dad asks "how are you today?" I reply that I am fine, good, great, even though I am really tired when he asked me how are you today.

I really don’t want to letmake him feel stressed and bad because I know he gothas a lot of pressure as a father who hasith two sons and a daughter.

Lying can helplet me to lethelp him feel good, isn’t iright?

The last example is how lying can make others not hurtkeep us from hurting others.

Not incorrect but the phrasing is a little strange.

I guess most of us are focusing our looking very mucha lot on our looks in theis period of our life even now, and sves. Some guys are really ugly ( I am sorry to say this).

Every time they ask me whether they are looking good.,

Combine the next sentence with this one; it's not a complete sentence
