The symbolic significance of the 14th National Mathematics Education Conference is to show the splendid civilization of ancient mathematics in China. The basic idea of icon design in the 14th National Mathematics Education Conference comes from the river map. He Tu and Luo Shu are the beginning of Chinese civilization. The Book of Changes says: Rivers draw pictures, Luo writes books, and saints write books. Later generations of Tai Chi, Eight Diagrams and Feng Shui can be traced back to this point. Hetu and Luoshu include the odd-even classification of numbers, the arrangement of arithmetic sum, magic square and other mathematical contents. In essence, it is a simple understanding of ancient logarithm and mathematics.
