Chinese jade bi disk

Is it possible that this jade disk, made during the Neolithic, or New Stone Age, symbolizes heaven? Why did ancient peoples in China, like people of the Liangzhu culture (c. 3000–2000 BCE) make them?

There is a lot of mystery surrounding jade disks and why they were made. Take a journey through time to ancient China to look at this deceptively simple looking object—jade is super hard to carve, so imagine having to create perfect circles!
