Generally, there are rural settlements before urban settlements. Urban settlements are generally more developed than rural science and technology, because people gradually feel the importance of science and technology in historical exploration. Science and technology are the primary productive forces, so we should attach importance to the development of science and technology.
Cities develop more industry and commerce, and rural areas develop more agriculture and animal husbandry. Industry is more conducive to economic development than agriculture, from which we can see the importance of economic strength, which often determines strength.
Therefore, the emergence of the city itself is produced in exploration.
