Which means it's enough to die when you hear about it (surface meaning, deep meaning) solution.

Now that we know the truth, let go of what we did wrong in the past and do it according to the rules from now on. This is superficial.

Dig deeper, "If you hear the word, you will die in the evening." The word' smell' here means that fame is reused by the rulers.

Confucius just said, "He who listens to the Tao dies in the evening." It seems that you can't convince everyone, so he went on to say, "A scholar should aim at Tao, and a person who is ashamed of food and clothing is enough to discuss." This is the origin of the word "Tao".

The word "Tao" in "Scholar is Tao" has the same meaning as "Wen Chao Tao". The "Tao" here refers to the political ideal, that is, benevolent government.

To sum up, it is easy for us to know that "smell in the morning and die at night." If in a country, if a person can realize the ideal he has always adhered to in the morning. Implemented his own political idea (benevolent government), so it was worthwhile for him to die at night.

Here, the word "knowing the truth" can never be simply regarded as "knowing the truth", which is a problem thousands of miles away.
