What is the relationship between the fourteen main stars and the twenty-eight main stars of Lagerstroemia indica?

Twenty-eight constellations are the division of Sunday constellations in ancient astronomy, which belongs to the astronomical category.

Fourteen main stars are the fourteen stars on Sunday, which are used in a divination method called "Wei Zi Dou Shu".

Of course, these 14 stars are all among the 28 stars, just with different names.
