Constellation: What do conjunction, positive phase and negative phase mean?

Phase combination is the synthesis of zero degrees between the phases of two planets.

Positive images are all good images, such as 0 (but auspicious), Sanlian 120 degrees, Liuhe 60 degrees and a half 30 degrees.

The negative phase is the phase image of the lost face, which coincides with 0 degree, deviates 180 degree, breaks 45 degrees, penetrates 135 degree, and hurts 150 degree.
