Why are ancient people in China so clever?

First, we must define intelligence. According to what definition? It can't be defined by building a car computer, that's now. The achievement of ancestors mainly depends on whether it is beneficial to future generations and whether it paves the way for the development of future generations. Wait a minute. If we do this and benefit future generations, it should be said that our ancestors were smart. From a scientific and technological point of view, Joseph Needham has a book, and all his collaborators' conference papers are online. It is said that the inventions of China's ancestors accounted for 40% of the world's patents in the past 3000 years! Is this smart? Go on. What if China's ancestors enacted the world patent law, which is not valid for 50 years, but for 5,000 years? At present, 40% of the global patent revenue will go to China! What are the four great inventions! Forty percent! What is the fate of those inventions that cover 40% of the world's current patents? Because no ancestors knew how to protect and develop these 40% inventions, many inventions were lost and re-invented after decades and hundreds of years! Even many times! Let's talk about Chinese characters again Chinese characters are two-dimensional, not spelling vowels and consonants. Our ancestors developed Chinese characters. There are more than 30 strokes in the most complicated Chinese characters, more than many letters in the alphabet. If the vowel consonant spelling method is used, according to the pinyin scheme, there are 2 1 initials and 35 finals. If only one symbol is used for each sound, and two symbols are not used to represent one sound, then there are only 56 symbols in the Chinese phonetic alphabet. Phonological spelling, 35x2 1=735 syllables, plus four tones, 735x4=2940 different sounds are spelled together. How easy it is to learn such a writing system! However, because of the use of two-dimensional Chinese characters, it has nothing to do with any characters in the world. What China people have learned with Chinese characters must be studied repeatedly in that kind of non-Chinese characters, such as English, in order to learn and learn any non-Chinese characters well! Moreover, many people can't learn it once, but they have to learn it many times! Ancestors, smart? However, ancestors can't change, and the dead can't enter! What about the living?
