Hi there! It sounds like your Da Fit watch switched to an Asian language after you charged it using a different brand charger. That’s a bit unusual but not impossible if the watch rebooted or reset during charging.

No worries! Let’s work together to get your watch back to your preferred language.

First, may I ask:
- Is your watch currently connected to the Da Fit app on your Windows 10 PC or a phone?
- Can you navigate the watch menus even though they're in the foreign language?
- Have you already tried reconnecting the watch to the Da Fit app since this happened?

Once I have this info, I can guide you specifically through the steps to change the language back. Generally, the process involves:

1. Connecting your watch to the Da Fit app via Bluetooth.
2. Opening the app’s device settings.
3. Finding the Language selection option (usually under Device > Other or Settings), then selecting English or your preferred language.
4. Confirming the change, which should update the watch display.

If you want, I can also guide you to do a factory reset on the watch, which will return it to default settings including language but may erase some data.

Let me know how you’d like to proceed and if you need me to walk you through the steps in detail!
