Baidu Post Bar and Baidu know which answer is more credible?

As for the question you mentioned, it actually depends on what kind of situation you are asking. It is the origin of the question that determines the truth of the answer. But there is still some difference between posting and knowing. Posting is more about discussing an event. Baidu knows that it is usually specific and personal.

And which side you say is more true is actually related to the professionalism of the questions you ask. For example, your questions are about science, medicine, mathematics, and these categories of science and engineering. Then the answer should be relatively uniform. Because science itself has the right answer. Therefore, there is not much difference between these correct questions with their own answers.
