What does the bee mean by jumping eight characters?

Bees crawl along a straight line and then turn left. Its moving line is 8-shaped, and it swings its abdomen. The angle between the central axis of the dance and the top of the nest just indicates the angle between the direction of honey source and the direction of the sun.

When bees dance, their heads are up or down, which is related to telling the direction of the honey source: when bees dance, their heads are up, which means they must fly in the direction of the sun to find the honey source; When dancing with your head down, it means that you must fly in the direction with your back to the sun in order to find the honey source; The speed of dancing is also related to the distance between the hive and the honey source: the farther the honey source is, the longer the bee wags its tail, and the longer the buzz it makes when wagging its tail.
