Where is Dayang at noon? Is this position called rabbit chicken line?

For China area, the direction of noon sun: the azimuth of noon sun is 180 (due south). The azimuth angle of the sun is generally the angle measured clockwise with the north direction of the target as the starting direction and the incident direction of the sun as the ending direction. The position of the sun is the position of the sun in the sky when viewed from the surface of the earth. It is a function of time and geographical location. When the earth orbits the sun for one year, the sun seems to follow a fixed path relative to the stars on the celestial sphere, which is called the ecliptic.
