First, the first half? Good medicine cannot cure injustice? The main meaning of this sentence is that no matter how precious and good the medicinal materials are, they can't cure injustice. The so-called unjust disease, in our definition, is not a good disease that can be suppressed by some medical means or taking some drugs. The disease belongs to a certain mental category because of my own psychological reasons. The main cause of unjust diseases is the living environment of patients or what has happened, which has a very serious impact on normal mental health. To treat this injustice, we can't treat it in the normal way of treating patients. Some special measures must be taken to relieve patients' mental stress or mental illness. So this situation can't be cured by taking medicine. I also got the saying that the bitter taste of good medicine is good for the disease, so we should prescribe the right medicine and use the right method.
The second half? Good words are hard to persuade fools? The main meaning to be expressed is that only some people are coaxed but others' opinions are not heard. The idiot here is not only the IQ of others, but the personality of this person may be too self-confident and very confident in himself. In our life, we will also encounter such a situation, that is, knowing that the other party may make mistakes or choose the wrong direction, we still try our best to persuade the other party, but others will not listen and there is no way. Generally speaking, for such people, only after letting them hit the south wall by themselves can they realize that they may have made a mistake. For a fool, it can only be said that it will be used in the wrong place, and it is futile to say more good things. I want to express a need through this proverb, that is, to focus on the right thing.
