Second, 99 is unified: one explanation is "in the final analysis" and the other is "going around many times and finally returning to the original". But these explanations are only a narrow and simple understanding of the meaning of idioms themselves. Although "99 ratio 1" refers to "cycle after cycle" or "in the final analysis", it is not the same cycle, but the movement process from the starting point to the end point, from the end point to the new starting point, cycle after cycle.
Third, it embodies the dialectical materialist philosophy's understanding of the development of all human things. There is a saying in Buddhism that "99 returns to one, and eventually it becomes a positive result." Here, "Nine" is the biggest and the most extreme, and it is regarded as the "most" in ancient and modern humanistic architecture. If we want to "go back to 1999 and finally make a positive result", we still need to "147, 369" and move forward step by step. ?
Fourth, 1999 returns to one, which means that you have never been here, gone out and returned to the original state. In fact, this reply is not a simple regression, but sublimation, re-creation, nirvana and a new starting point. Because nine is the largest positive number and twelve is the largest negative number.
So 99 is the biggest, return to the original one.
