How many areas is the whole sky divided into?

1928 in order to meet the needs of astronomical research, the general meeting of the international astronomical union held in Leiden, the Netherlands clearly divided the whole sky into 88 constellation areas;

These 88 all-sky constellation regions are divided according to the zigzag boundary between right ascension and right latitude along the celestial equatorial coordinate system. After the division, the traditional names of constellations are retained, and their scientific names are specified in Latin. The abbreviations are composed of three clear letters, which are used uniformly all over the world.

China's ancient division of the whole sky.

In ancient China, the whole Temple of Heaven was divided by the stars, and the most important one was the 28 halls with three walls. These three walls mean that the sky around the North Pole and overhead is divided into three areas, namely Ziwei Garden, Taiwei Garden and Shi Tian Wall.

But around the ecliptic and the celestial equator, it is divided into four elephants.

In "Four Elephants", each elephant is subdivided into seven areas, which are collectively called twenty-eight lodges. These are the unique names of constellations in China. In modern times, in order to facilitate scientific research, the international all-sky division was adopted.
