Learn Hardcore Chinese: Tā měitiān xiàbān hòu dōu qù gōngyuán, ránhòu cóng gōngyuán zǒu dào jiā. - Every day after work, she goes to the park, then walks home from the park.

都 distributes the action over a set. The set here is the days introduced by 每天. So it means she does it every single day, without exception.
It doesn’t count people in this sentence; it emphasizes regularity across days and sounds very natural.

Where should 都 go in this sentence?

Put 都 after the subject (or topic) and after the thing that creates the set, but before the main verb.
Natural: 她每天下班后都去公园。 / 每天她下班后都去公园。
Avoid placing 都 so that it seems to modify the time phrase itself or the subject alone.

Can I omit 都?

Yes. 她每天下班后去公园 is grammatical and clear. Using 都 adds emphasis and is extremely common with 每-words.

What about the word order of the time expressions 每天 and 下班后?

Both 她每天下班后… and 每天她下班后… are fine. The first is more common; the second puts extra emphasis on “every day.”
她下班后每天都去公园 is also possible and slightly emphasizes the “after work” time window. Don’t split 下班后.

What’s the difference between 后, 之后, and 以后 in 下班后?

下班后 and 下班以后 are near-synonyms; 以后 can feel a bit more open-ended, but in daily use there’s little difference.
下班之后 is fine and a bit more formal/literary.
For immediate sequence you can also use 一…就…: 她每天一下班就去公园.

Why is 然后 used? Could I drop it or use something else?

然后 means “then/after that” and sequences the actions.
You can drop it and just use a comma: …，从公园走到家。
Alternatives: 接着 (next), 之后 (afterwards). Don’t use 后来 for a routine; 后来 is for narrating past events.

Why repeat 公园? Could I just say 然后走回家?

Why use 走到家 instead of just 走家?

走 needs a complement to indicate reaching a place. 走到家 uses the result complement 到 (“arrive”).
走家 is ungrammatical. Without 到, a common alternative is 走回家 (“walk back home”).

What’s the difference among 走到家, 走回家, and 回到家?

走到家: focuses on arriving home on foot (completion).
走回家: focuses on the direction “back home” on foot; often used for plans/habits.
回到家: focuses on “back and arrived (at) home,” no transport specified. With 走, use 走到家 or 走回家, not 走回到家.

Why is it 从公园走到家 and not 走从公园到家?

With motion verbs plus result complements, use: 从 + 起点 + V + 到 + 终点 → 从公园走到家.
Putting 从…到… after the verb isn’t used with 走到. With other structures you can say: 我从公园到家坐公交 (I take the bus from the park to home).

Can I say 然后从公园到家 without a verb?

Not as a predicate. 从公园到家 needs a verb or predicate, e.g., 从公园到家要走三十分钟 or 从公园走到家.

Is 去公园 the only natural way? What about 到公园 or 到公园去?

去公园 is the simplest “go to the park.”
到公园 emphasizes arrival; 到公园去 is also common. All work here with minor nuance differences.

Do I need 了 anywhere?

Is the subject omitted in the second clause? Is it still 她?

Yes. Chinese often omits repeated subjects. After ，然后, the subject remains 她 unless context changes it. You may add it (然后她…) for clarity/emphasis.

Is 家 or 家里 more natural here?

到家/回家 are the idiomatic choices. 到家里/回到家里 is possible but less common and can stress the interior specifically. For routes/habits, prefer 到家 or 回家.

Could I add 就 to highlight immediacy?

Yes: 她每天下班后就去公园，然后就从公园走回家。 就 makes the sequence feel more immediate and is very natural in speech.

Pronunciation check: any tricky tones here?
