copilot made a poster for me but not expected simplified Chinese

To get posters from Microsoft 365 Copilot in Simplified Chinese, configure both the input method and the language you use in the prompt:

1. Add Simplified Chinese input in Windows (if not already added):
   1. Open Settings > Time & language > Language & region.
   2. Select Add a language and choose Chinese (Simplified, China), then select Next and Install.
   3. This installs the Microsoft Pinyin IME by default so Simplified Chinese can be typed.
2. (Optional) Add Microsoft Wubi IME if preferred:
   1. On the Language & region page, select the … next to Chinese (Simplified, China) and choose Language options.
   2. Under Keyboards, select Add a keyboard and choose Microsoft Wubi.
3. Type the prompt in Simplified Chinese when creating the poster:
   1. In the Microsoft 365 Copilot app, select Create in the left navigation.
   2. Select Poster.
   3. Switch the input method to Chinese (Simplified) (Pinyin or Wubi) from the taskbar.
   4. Enter the poster description directly in Simplified Chinese in the prompt box (for example, describing the event, style, and text you want on the poster in Simplified Chinese).
   5. Select Create.
4. If the generated poster still contains non‑Chinese text:
   1. Use Transform with AI and explicitly request Simplified Chinese text (for example, “请将所有文字改为简体中文”).
   2. Select Edit to manually change any remaining text boxes to Simplified Chinese using the IME.
5. Save or reuse the design:
   1. When satisfied, select Download.
   2. Posters can be found later in Copilot Library as described in the poster design help.

If the environment supports Simplified Chinese generally (as listed for Microsoft Copilot text-based responses), prompts and generated text in Simplified Chinese should be honored when the prompt itself is written in Simplified Chinese.
