Hi Printhana,
We'll be glad to assist. If you're not receiving sounds or vibration, it may be possible that your watch is set to mute. If so, the steps in Change the audio and notification settings on your Apple Watch - Apple Support will help you to resolve this.
"How to mute your Apple Watch
- Touch and hold the bottom of the watch face. Wait for Control Center to show, then swipe up.
- Tap the Silent Mode button
. This turns on Silent Mode. You can still receive haptic notifications.

To silence an alert or notification as it sounds, rest your palm on the display for at least three seconds or until you feel a tap. If it doesn't work, see if the Cover to Mute setting is on: On your iPhone, open the Apple Watch app, go to the My Watch tab, then tap Sounds & Haptics."
Cheers.
