[Yuhuan]
Yuhuan has an outer diameter of 9 cm, an aperture of 6.2 cm and a thickness of 1.3 cm. Lingjiatan Culture in the Neolithic Age
Yuhuan has been eroded into tooth color due to the Qin, with thin outer edge, thick near the hole, and nearly triangular profile. This ring is regular in shape, plain and smooth in grinding
There are many annular implements unearthed from Hanshan culture, but this one is the most exquisite. Yuhuan has been unearthed in many places in various cultures of the Neolithic Age, with a large number. However, it is very rare that its profile is triangular, which has a great impact on the later generations, especially in the Warring States Period
This Yuhuan was unearthed from Lingjiatan Tomb in Hanshan County, Anhui Province in 1987
