In the principle of the parties answering the judge's questions, clarity comes first, and clarity means that it cannot be yes or no, cannot hesitate, cannot look left and right, and cannot be ambiguous, but must be direct so that the questioner understands what you mean.
Unclear answers, for example: it could be, it seems to be, he or he, I remember it seems to be, I can't remember what it seems to be, that person should be him, 8% probability or more, etc. In short, the result of this unclear answer is that you say that you don't even believe yourself, so how can the judge believe it. The judge's first thought of such an answer was that it was not credible.
Clear answer, for example: yes, yes, correct, he is my friend, he went that day, he was in that place that day, he didn't lend me money, the other party defaulted, I don't know, I don't know, I don't understand (not clear, don't know, don't understand is also a clear answer, when you don't know, not clear is the clearest way to answer).
A clear answer to a question is a clear expression of the point of view on a particular detail of the case, and failure to answer a question clearly is not only unhelpful but also potentially disadvantageous.
