Why sometimes the moon is too low to shine high in the sky, just like today (Quanzhou, Fujian, August 12)?

This phenomenon is related to the revolution of the moon. If the moon does not revolve, its spatial position with the sun will not change, so the time of sunrise and moonrise is basically fixed every day.

Because the moon moves around the earth from west to east, one cycle is about 27 days, that is, it moves eastward about 13 degrees every day. Therefore, the day when the moon rises, it will be delayed by 52 minutes every day. For example, the full moon comes out at sunset, but after 7 days, the last quarter moon comes out at midnight.

Today (12 August) is the 19th lunar month. The moon rises about 16 hours later than the sun and doesn't come out until after midnight, so genius will rise to a very high position.
