Is there no reminder for WeChat to receive red envelopes?

That's probably because your mobile phone WeChat doesn't turn on the voice reminder, and there will be a sound when it is set.

Take "Mobile WeChat Version 8.0.28" as an example to explain the operation steps:

1. Open the mobile phone WeChat-click "I" in the lower right corner-select "Settings", as shown:

2. Find "New Message Notification" in "Settings", as shown:

3. In "New Message Notification", find "ringtone" in "Prompt tone and ringtone".

4. Click Enter, play the ringtone, and turn the volume of mobile media to the maximum, as shown in the figure below:

With this set, if you receive a red envelope on WeChat, there will be a sound.
