Sunzi Suanjing is one of the ten books of Suanjing, an arithmetic textbook in the early Tang Dynasty. It has three volumes. The first volume describes the system of counting, multiplication and division, and the middle volume illustrates the method of calculating scores and Kaiping with examples, which are all important materials for understanding the ancient calculation in China. The second book collected some arithmetic problems.

It is of great significance to Volume 26: "There are unknown things today. Three and three numbers leave two, five and five numbers leave three, and seven and seven numbers leave two. What is the geometry of things? Answer:' Twenty-three' ". Sun Tzu's calculation not only provides the answer, but also gives the solution.
Qin, a great mathematician in the Southern Song Dynasty, further initiated the research work of congruence theory and popularized the problem that "things are unknown". Gauss, a German mathematician, clearly wrote the above theorem in "Arithmetic Inquiry" published in A.D. 180 1.
In A.D. 1852, the British Christian priest Vias spread the solution to the problem of "unknown things" in Sun Tzu's calculation to Europe. In A.D. 1874, Mathiesen pointed out that Sun Tzu's solution conformed to Gauss theorem, thus calling this theorem "China's remainder theorem" in the history of western mathematics.
