"What you hear is false, what you see is true" means that the information you get from others may not be true, and only what you see with your own eyes can be used as a reliable basis. The meaning of this sentence is that we can't completely believe what others say, and we need to observe and understand it ourselves before we can come to a truly correct conclusion.

The meaning of this sentence is to warn us not to believe what others say, not to believe other people's speculation easily, but to judge after seeing the truth with our own eyes. Because people's experiences and opinions are different, and some people may distort information in a general way or deliberately, so sometimes the information they hear is not necessarily true.

Therefore, we should accumulate real knowledge and information based on our own senses through personal observation or practice, and then we can make an objective and accurate judgment when we meet important decisions. In fact, this sentence also reminds us that we should treat some unconfirmed rumors or rumors with suspicion, and we should not believe or spread them easily to avoid misleading and spreading false information.

When we communicate with people or understand things, we need to be skeptical and cautious at all times, and we don't trust others' opinions or judgments easily. At the same time, we need various evidences to verify them, so as to avoid being deeply cheated. Only by observing and proving in many ways can we draw a real conclusion and clarify our own views.

Of course, this sentence does not unconditionally deny the value of what others say. Sometimes the prejudice and experience of others may also bring us enlightenment and beneficial experience. Therefore, we should judge according to different situations, while listening to others' opinions and combining our own actual situation, so as to better understand and apply others' information and opinions.

what you hear is the source of what you see is what you believe
