The angle between the moon, the Earth, and the sun changes over a month, and since we only see the side of the moon that is reflecting the sun's light, it seems that the moon appears differently.
The combination of the light from the sun and the moon's orbit around Earth causes the moon to appear differently at different times during the month. This creates the phases of the moon, such as the new moon, full moon, and crescent moon, as we observe from Earth.
If you look at the stars at the same clock-time every night, the whole picture will appear to rotate 1 degree per day, 30 degrees per month.
I would guess that Hong Kong is closer to the equator, compared to some other place where you lived, and with which you are comparing it. Of course that question must mean "overhead around noon". Hong Kong is more or less on the Tropic of Cancer. The Sun can appear overhead as far north as the Tropic of Cancer around the summer solstice (about June 21st).

Over the course of a month, Earth rotates on its axis approximately 30 times and orbits around the Sun once. Meanwhile, the Moon orbits around Earth approximately 12-13 times, causing its phases to change from new moon to full moon and back.
A 9 month old male Labrador might appear to have 2 sets of testicles because he has swelling or damage to the testicles. He might also have a bite or infection that causes the area to appear doubled.

A new moon may appear once or twice each month.
The first Lincoln cents were put into circulation in August, 1909. Of course the coins were minted before that but weren't released.

None of them. You need an event.

the earth is rotating and revolving, so they are appear in different places
Constellations appear to move across the sky due to the Earth's rotation. Over the course of a month, the position of the Earth changes in its orbit around the Sun, causing the night sky to gradually shift and different constellations to become visible.
A month is when the earth rotates 1 12th around the sun
