I asked a question in Baidu. How did the respondent know my phone number? Solve? They sent text messages to my mobile phone, which is really strange, Baidu's confidentiality.

Don't doubt the landlord! There are three possibilities. First, ask questions on your mobile phone, and the answers will be automatically sent to your mobile phone. Second, you wrote your mobile phone number in your space or other personal data, so you can look it up. If yes, please delete it, so that others can't see your mobile phone number. Third, you inadvertently revealed your mobile phone number when answering or asking questions.

Nothing, just pay attention in the future. I wish Baidu a pleasant journey and good luck!
