I heard Xiao Zhengzhen talk about this on his official website.
The innate table of Chinese characters will never change. When you are born, the date of birth corresponds to a chart.
But counting the ten-year lucky or fleeting time, both the Trinity School and the Flying Star School will have fleeting flying stars. That's not because fate has changed, but the people of that faction have different methods of analysis.
Mr. Xiaozhengzhen said that when the Tao is simple, you should first learn to look at the constellations. If you understand it, you don't have to look at the stars flying all over the sky.
