The Fu Xi is a distance driver rated 12/6/-1/2, one speed point slower than Yikun's She Gong. Yikun emphasises its glide rather than raw stability. It is not a beginner's driver: a thrower who cannot bring a speed 12 up to pace may see an earlier fade and get more distance from a slower mold.
Yikun describes it as a high-speed long-distance disc with exceptional gliding, and says experienced players can achieve distances surpassing other disc types. The -1 turn suggests modest high-speed movement rather than pronounced understability, and the 2 fade a moderate finish rather than a hard dump.
PDGA certified it on 20 March 2023 under the name Serpentine (伏羲, Fú Xī). Yikun's product title advertises the Glaze Line while the same page's material field and our own plastics data say Glaze X, so treat the line name on any given run with care. Yikun markets Glaze X on its ceramic-like appearance and radiant-line pattern.

DiameterHow wide the disc is, edge to edge. Almost every disc is 21 to 22 cm.
21.2 cm
HeightHow tall the disc is lying flat. Putters are usually the tallest.
1.6 cm
Rim DepthHow deep the rim is underneath, where your fingers grip. Putters have the deepest rims.
1.2 cm
Rim ThicknessHow wide the rim is. Wider rims make faster discs that need a stronger throw.
2.3 cm
Rim Inside DiameterThe width of the flat middle, inside the rim. Bigger usually means a slower, easier disc.
16.6 cm
Rim Depth/Diameter RatioRim depth as a share of the disc's width. Higher means a deeper rim for its size.

Rim ConfigurationA PDGA score for the shape of the edge. Low is sharp, like a driver. High is rounded, like a putter.

BeadA small ridge under the edge of the rim, mostly on putters. It changes how the disc feels in hand.
