Here are the corrections:

1. (x) When get a good new We said dinner is on you.
   (o) When we get good news, we say, "Dinner is on you!"
   Explanation:

   • "When get a good new" → Needs a subject ("we") and correct phrasing: "When we get good news."
   • "Said" → Should be "say" for a general statement.
   • "Good new" → "News" is uncountable, so "good news" is correct.

2. (x) We treat it.
   (o) We celebrate it.
   Explanation:

   • "Treat" is incorrect in this context; "celebrate" is the correct verb for marking an occasion.

3. (x) We hold a party with sincerely closer.
   (o) We hold a party with close friends and colleagues.
   Explanation:

   • "Sincerely closer" is incorrect. The correct phrase is "close friends and colleagues."

4. (x) Someone get promoted is on dinner and invite to celebrate with co-work after set up each other's time available and to do place.
   (o) When someone gets promoted, they host a dinner and invite coworkers to celebrate after setting a time and choosing a place.
   Explanation:

   • "Someone get promoted" → Should be "someone gets promoted" (subject-verb agreement).
   • "Is on dinner" → Unclear phrase; "they host a dinner" is correct.
   • "Co-work" → Should be "coworkers."
   • "After set up each other's time available and to do place" → Needs rewording for clarity.

5. (x) Usually closer people hang out.
   (o) Usually, close friends hang out together.
   Explanation:

   • "Closer people" is unnatural; "close friends" sounds better.
   • "Hang out" → Adding "together" makes the sentence clearer.

6. (x) Or in official staff party we congratulate together.
   (o) At official staff parties, we celebrate together.
   Explanation:

   • "Or" is unnecessary.
   • "In official staff party" → Should be "At official staff parties" (plural and correct preposition).
   • "Congratulate together" is unnatural; "celebrate together" is better.

7. (x) We can notice already who will promoted.
   (o) We can already tell who will be promoted.
   Explanation:

   • "Notice already" → Should be "already tell" for natural phrasing.
   • "Who will promoted" → Should be "who will be promoted" (correct verb form).

8. (x) Usally it getting work in longer, it has a little priority.
   (o) Usually, those who have worked longer get priority.
   Explanation:

   • "Usally" → Spelling error, should be "Usually."
   • "It getting work in longer" → Needs rewording for clarity.
   • "It has a little priority" → "Get priority" is more natural.

9. (x) We alreay prepare his present or congratulate.
   (o) We already prepare a gift or congratulate them.
   Explanation:

   • "Alreay" → Spelling error, should be "already."
   • "His present" → "A gift" is more general.
   • "Or congratulate" → Needs "them" as an object.

10. (x) It seems to different To each his own.
    (o) It seems different for everyone. To each their own.
    Explanation:

    • "It seems to different" → Should be "It seems different for everyone."
    • "To each his own" → "Their" is more inclusive than "his."

Final Edited Text:

When we get good news, we say, "Dinner is on you!" We celebrate by holding a party with close friends and colleagues. When someone gets promoted, they host a dinner and invite coworkers to celebrate after setting a time and choosing a place. Usually, close friends hang out together, or at official staff parties, we celebrate as a group. 

We can already tell who will be promoted. Usually, those who have worked longer get priority. We already prepare a gift or congratulate them in advance. Everyone has their own way of celebrating—it seems different for everyone. To each their own!
