The inheritance and reproduction of human wisdom and the exploration of empirical science have made unprecedented scientific and technological progress in the twentieth century. However, human confusion is not less than before, but more than before. As Newton said, if knowledge is round, then its interior is known and its exterior is unknown. The more you know, the bigger your circle is, and the more unknown you are exposed to. The western proverb says that "science is the daughter of doubt", and curiosity is the driving force of all scientific and technological exploration. We encourage human curiosity, because with curiosity, there will be a vibrant human being and a scientific world of "continuous progress, continuous growth and continuous growth day by day".

The expansion of curiosity will inevitably raise all kinds of mysterious, wise or naive and stupid questions. As the western proverb says, "one stupid person can ask more questions than ten smart people can answer." In fact, it is not necessarily a fool who can ask endless questions, such as Qu Yuan's Tian Wen. If you don't want to obey the traditional rules, you can travel to Wan Ren, and you must have the idea of surpassing your predecessors.
