比起 introduces a comparison in a slightly broader, more topic-setting way than plain 比.

• A 比 B + adjective = the basic pattern for direct comparison
• 比起 A, B ... = compared with A, B ...

So here, 比起别人从来不看说明，... sets up the comparison first, and then the main point comes after the comma.

A more basic comparison might look like:

• 他比别人更安心。

But 比起 often feels more like when compared with... or compared to....

The comparison is between him and other people who never read instructions.

The key clue is 更, which means more. Chinese often does not repeat every part of the comparison if the context already makes it clear.

So the sentence is compressed. The fuller idea is something like:

• compared with other people who never read instructions, he feels more at ease
• or, compared with them, he feels more reassured about his own way

A more explicit version could be:

• 比起那些从来不看说明的人，他觉得自己看了说明更安心。

That version spells out more of what is only implied in the original.

从来不 means never.

So:

• 从来不看说明 = never reads the instructions

This is a very common pattern:

• 我从来不喝咖啡。 = I never drink coffee.
• 他从来不迟到。 = He is never late.

A useful thing to know: 从来 is very often used with a negative word such as 不 or 没.

• 从来不 + verb = never does
• 从来没 + verb/过 = has never done

This is because of tone change.

不 is normally fourth tone: bù.
But when 不 comes before another fourth-tone syllable, it changes to second tone: bú.

Here:

• 看 is fourth tone: kàn
• so 不看 is pronounced bú kàn

This is a pronunciation rule only. The character still stays 不.

别人 is the normal, very common way to say other people or others.

So:

• 别人从来不看说明 = other people never read instructions

You could also say:

• 别的人
• 其他人

But 别人 is shorter and more natural in many everyday contexts.

Very roughly:

• 别人 = others / other people
• 别的人 = other people, with a slightly more literal feel
• 其他人 = other people / the rest, often a bit more formal or neutral

Here 说明 means something like instructions or explanatory information.

After 看, it is being used like a noun:

• 看说明 = read the instructions / read the explanation

In daily life, many speakers would also say:

• 看说明书 = read the manual / instruction booklet

The difference is:

• 说明 can mean explanation, instructions, or even to explain depending on context
• 说明书 specifically means an instruction manual or booklet

So in this sentence, 说明 is understandable, but 说明书 might feel a bit more concrete in some situations.

自己 refers back to the subject and means oneself / himself / herself, depending on context.

So:

• 他觉得自己更安心 = he feels that he himself is more at ease

If you said:

• 他觉得他更安心

that could be ambiguous, because 他 might refer to a different male person.

Using 自己 makes it clear that the feeling is about the same person as the subject.

更 means more or even more.

It marks the comparative part of the sentence:

• 更安心 = more at ease / more reassured

Because the sentence already begins with 比起..., the comparison is already set up, so 更 fits naturally.

Compare:

• 安心 = at ease
• 更安心 = more at ease

In this sentence, 更 connects back to the comparison introduced by 比起.

In this sentence, 安心 works like an adjective or state word meaning at ease, reassured, or free from worry.

So:

• 觉得自己更安心 = feel more at ease

Chinese words are often flexible, so 安心 can appear in different kinds of structures:

• 我很安心。 = I feel at ease.
• 这样做让人安心。 = Doing it this way reassures people.
• 你安心吧。 = Don’t worry / Be at ease.

Here, after 觉得, it describes a state.

Because 别人从来不看说明 is being used as a whole clause, not as a noun modifier with 的.

In other words, it is structured more like:

• other people never read instructions

not:

• the people who never read instructions

If you wanted a more explicit noun phrase, you could say:

• 那些从来不看说明的人

That would mean:

• those people who never read instructions

So the original sentence is a bit more compact, while the version with 的人 is more spelled out.

Yes. It is understandable, but it is somewhat compressed.

A learner may feel that something is implied rather than fully stated. That is normal in Chinese, especially when the context already makes the missing idea obvious.

Many speakers might make it clearer by saying something like:

• 比起那些从来不看说明的人，他觉得自己看了说明更安心。
• 别人从来不看说明，但他觉得自己还是看了说明更安心。

These versions make the logic more explicit: the reason he feels more at ease is that he reads the instructions, unlike those other people.

So if the original feels slightly tight or compact, that is a reasonable reaction.

Sometimes yes, depending on context.

比起 often means compared with, but in some sentences it can feel close to rather than or as opposed to.

For example:

• 比起红茶，我更喜欢咖啡。 = Compared with black tea, I prefer coffee.
• This can also feel a bit like: rather than black tea, I prefer coffee.

In your sentence, the strongest reading is still compared with. But because the comparison also implies a contrast in behavior, English may sometimes express that contrast with phrasing like instead of doing what others do....

Yes. If you want the structure to be clearer, you could say:

• 比起那些从来不看说明的人，他觉得自己看说明更安心。
• 别人从来不看说明，但他觉得自己看了说明会更安心。

These versions help because they make two things more explicit:

• who exactly 别人 refers to
• what action makes him feel 更安心

The original sentence is not impossible, but for study purposes, a slightly fuller version is often easier to understand.
