What constellations can Hainan see _ What constellations can Hainan see?

Can you see the Big Dipper at the low latitude of the earth in Sanya, the southernmost tip of Hainan Island in China? Or Polaris?

Just like when you look at the wheel, the center is always in the same place, but the outside is turning. The earth's axis points to Polaris, so the position of Polaris doesn't change much, and all the stars revolve around it. The Big Dipper is close to the North Star, and all the movements are very small. The minimum size is 0 degrees. You can see it unless it's at the foot of the mountain or in a well. On a cloudy day, the blind don't know the North Star ... just draw a schematic diagram. Some parts of the southern hemisphere should be invisible, while others are obscured.
