péngyou zhù wǒ gōngzuò shùnlì.

The pattern is:

Subject + 祝 + person + wished-for result

So here we have:

• 朋友 = the subject, friend / friends
• 祝 = to wish
• 我 = the person receiving the wish, me
• 工作顺利 = the content of the wish, that work goes smoothly

So Chinese is literally structured more like:

Friend(s) wish me work-go-smoothly.

Because 祝 usually takes the person receiving the wish first.

A very common pattern is:

祝 + someone + positive phrase

Examples:

• 祝你生日快乐。 = Wish you a happy birthday.
• 祝你一路平安。 = Wish you a safe journey.
• 祝我工作顺利。 = Wish me smooth work / success in my work.

So 我 comes right after 祝 because it is the person being wished well.

工作顺利 means something like:

• work goes smoothly
• things go well at work
• success in your work

It is a very natural Chinese wish expression.
Chinese often uses short, compact phrases like this instead of a full English-style clause.

So rather than saying something long like I wish that your work will go smoothly, Chinese can simply say:

祝你工作顺利。

Here it is best understood as part of the phrase 工作顺利, where 工作 is basically work / job and 顺利 describes how it is going.

So the idea is:

• 工作 = work
• 顺利 = smooth / going well

Together: work is going smoothly

Even though 工作 can also be a verb meaning to work, in this sentence the whole phrase is understood as one's work goes smoothly.

Because in Chinese, adjectives can often act directly as predicates.

In English, you need to be:

• My work is smooth
• Things are going well

In Chinese, you often do not need 是 before an adjective:

• 工作顺利
• 身体健康
• 学习认真

So 顺利 can directly describe the situation without 是.

Chinese often leaves out words like that when introducing the content of a thought, wish, or statement.

English might say:

• My friend wishes that my work goes smoothly.

Chinese simply says:

• 朋友祝我工作顺利。

The wished-for idea comes directly after 我, without needing a separate word for that.

Chinese often leaves out possessives when the relationship is clear from context.

So 朋友 can mean:

• a friend
• my friend
• friends

depending on context.

If you want to make it explicit, you can say:

• 我的朋友祝我工作顺利。 = My friend wishes me success in my work.

Without 我的, the sentence is still grammatical; it is just less specific on its own.

Because Chinese nouns usually do not have to show singular or plural.

So 朋友 can mean:

• friend
• friends

depending on the situation.

You can add 们 if you specifically mean a definite group of people:

• 朋友们祝我工作顺利。 = My friends wish me success in my work.

But very often Chinese leaves number unstated unless it matters.

祝 is common and natural, especially in:

• greetings
• messages
• cards
• speeches
• polite good wishes

It can sound a bit more purposeful or formulaic than plain 希望.

For example:

• 祝你工作顺利。 = a standard good wish
• 希望你工作顺利。 = I hope your work goes smoothly

Both are fine, but 祝 is especially common in set expressions of goodwill.

朋友 is pronounced péngyou.

Important point: the second syllable you is usually in a neutral tone, not a full third tone.

So it sounds like:

• péngyou

not

• péng yǒu

This is a very common pronunciation pattern for 朋友 in natural speech.

Yes. This pattern is extremely useful.

You can replace 我 and the final phrase:

• 祝你工作顺利。 = Wish you success in your work.
• 祝你学习进步。 = Wish you progress in your studies.
• 祝你身体健康。 = Wish you good health.
• 祝你一路平安。 = Wish you a safe trip.

So a very productive pattern is:

祝 + person + positive result

It is one of the most useful polite patterns in Mandarin.
