The WeChat red envelope has a deadline. If it is not collected within the deadline, the red envelope will be automatically returned to the original account. The specific return time depends on the settings of the sender of the red envelope, but it generally does not exceed 24 hours. The red envelope has expired and will be returned automatically after it is collected. Therefore, the WeChat red envelope did not understand the automatic return.

Although the WeChat red envelope did not understand the automatic return, it is recommended to collect it in time after receiving the red envelope to avoid overdue return.
