1 .9 and 5 are the best numbers. Because the ninth five-year plan is supreme, the figures used by the emperor are absolutely auspicious, and the people must be lucky when they use them.
2. In ancient China, numbers were divided into positive and negative numbers, odd numbers were positive and even numbers were negative. Nine is the highest yang number, with five in the middle, so "nine" and "five" symbolize the authority of the emperor and are called "the supreme of the ninth five-year plan".
3. Counting from the bottom up, the fifth one is called the Ninth Five-Year Plan, nine means this one is Yang, and five means the fifth one. Because of the Yin-Yang transformation of the Yijing, the flourishing age is bound to decline, so the Ninth Five-Year Plan is "flying over the sky" and the Ninth Five-Year Plan (six-year plan) is "kanglong has regrets".
4. The Ninth Five-Year Plan is the best of the dry hexagrams, and the dry hexagrams are the first of the sixty-four hexagrams, so the Ninth Five-Year Plan is the best of the sixty-four hexagrams and the three hundred and eighty-four hexagrams, which has become the emperor's phase.
It is said that there are 14 dragons, nine earthworms and five hoses in China. The ancient emperors thought that "the dragon is mighty, worships and worships, and I am the only one in the world", so it was called "the Ninth Five-Year Plan" or "the real dragon emperor".
