Today, WeChat officials issued a formal response through the "WeChat Pai" public account as to why WeChat does not have a read function:"Read" means "saw it but didn't reply to you". This can lead to suspicion and anxiety, and even urge the other party to reply immediately. Without the read function, the choice of "respond or not" is returned to the user's hands.
Different from "read", "the other party is typing" is a limited status prompt, which only conveys the information that the other party is online and ready to reply. It can not only retain the real-time sense of the conversation, but also leave space for both parties to think and be silent, while taking into account the needs of mobile phone power saving and data saving.

In response to a netizen's message "Never show the read function", WeChat officially replied "Definitely not" and made it clear that this function will not be launched.
The published article also explains the trigger conditions for "the other party is typing": it must also meet the following requirements: after the user sends the message, the other party opens the dialog box within 10 seconds, and there is a typing action (including spaces) in the input box.

This prompt is implemented based on the "signaling handshake" mechanism and is not continuously connected to the network, so it will be displayed intermittently.
In addition, Tencent’s public relations director Zhang Jun has made it clear many times before that WeChat has firmly not provided a “read” function since its launch.It will not be launched in the future. The core reason is to avoid increasing the psychological burden and social pressure on users.
