What does the astrolabe 30 50' stand for?

Constellation 12 is 30 degrees per house, which can be divided into three equal parts, and each equal part is 10 degrees.

0~9 degrees is the first ten-degree interval of degrees.

10~ 19 degrees is the second ten-degree interval.

20~29 degrees is the third ten-degree interval.

Generally speaking, the planets in the first decadal interval are the strongest, which can give full play to the characteristics of the constellation, while the second and third decadal intervals are weak, which makes it difficult to show the typical characteristics of the constellation, and each decadal interval will imply a certain constellation character (fire and geomantic omen) which is the same as the constellation elements.
