How did Chinese deal with a scientific problem: Building the solar eclipse theory in ancient China (the 7th-10th century AD)

In the 6th century, the phenomena of irregularity of the solar motion and parallax of the moon were found by Chinese astronomers. This made the calculation of solar eclipse much more complex than before. The strategy that Chinese calendar-makers dealt with was different from the geometrical model system like Greek astronomers taken as. What Chinese astronomers chose is a numerical algorithm system which was widely taken as a thinking mode to construct the theory of mathematical astronomy in old China.
