How did I receive the text message that Baidu knew?

It's not a scam message. Don't worry. This is a short message that Baidu knows. When a netizen answers your question, Baidu knows that it will send the best answer to your mobile phone. Receiving answers and Baidu receiving information are free, and the received information does not need to pay any fees.

I think this function is still very practical for users. If you don't want this function, you can go to the personal center to cancel the setting.
