I get at least dozens of phone calls every day, saying that I am from Baidu and I am doing promotion. Ask Baidu: Is this true? Does Baidu really need to do this?

It's basically true. Promoting bidding is a means for the rapid growth of small and medium-sized enterprises, so it is normal for companies to call for inquiry, and there must be competition within the company, so it is normal to receive many calls a day. It is recommended to protect your privacy and keep your mobile phone number confidential in the future. There is no need to hang up directly for this kind of sales call. Please understand.
