I have seen just an interesting Screenshot on Facebook which arranges me to think anew about this question.
»If the words are wrong, then what they say is not meant. If what is said is not true, then the works are not right. If the works do not thrive, customs and arts will be spoiled.
Therefore, make sure that the words are correct. That’s the most important thing of all.«
(Confucius (551-479 BC), Chinese philosopher, responsible for the social and social order of China)
