China's Euclid is called Liu Hui, and Liu Hui is Newton in the field of mathematics in the history of China. His representative work, Nine Chapters Arithmetic, is the most important classic mathematical work of China, which laid the foundation for the development of ancient mathematics in China and occupies an extremely important position in the history of Chinese mathematics.

Liu Hui has quick thinking and flexible methods. He advocates reasoning and intuition. He was the first person in China who explicitly advocated using logical reasoning to demonstrate mathematical propositions. Liu Hui's life is a life of hard exploration of mathematics. Although his position is low, his personality is noble. He is not a mediocre man who seeks fame and fame, but a great man who never tires of learning. He left us a valuable fortune.
