Before the American Civil War, when slaves fled from the south to the north at night, they conveyed "walking in the direction of the constellation like drinking spoons." What does this constellation mean? It should be the Big Dipper, which is the seven stars in the tail of Ursa major.

There are many descriptions about the shape of the Big Dipper. Some people say it is like a spoon, others say it is like a tube, and of course some people say it is like a drinking spoon.

Connect the two stars at the end of the Big Dipper and extend it in one direction for five times, and you will see a bright star-Polaris. Many people use this star to tell the direction-this star is on the straight line of the earth's axis, so people always look at it in the north (unless they look at it in the North Pole).
