How many constellations are the stars in the sky divided into by region?

The ancients in China divided the stars in the sky into four groups:

There are dragons in the east, suzaku in the south, white tigers in the west and Xuanwu in the north.

Each group contains seven "huts", which together are "28 huts".

There is also a "Ziweiyuan"-the Big Dipper.

Each star has a name: Tianjin IV, Beiluo Shimen, Hegu III, Xuanyuan XIV, Weaver Girl, Cowherd and so on.

Westerners divide the stars in the sky into 88 constellations and name each constellation with ancient Greek fairy tales:

(1) Polaris constellations: Ursa minor, Dragon Constellation, Cepheus, Andromeda, Deer Leopard, Ursa major, Shepherd Constellation, Coronation North, Five Immortals, Lyra, Cygnus, Scorpion, Andromeda, Perseus, Auriga, Tmall Constellation, Little Lion Constellation and Houpai Constellation.

Westerners found the stars that can be seen in the southern hemisphere after sailing around the world, so they had the Southern Constellation. China people didn't see it in ancient times, so there was no Southern Constellation.
