Shark's fins are simply divided into two categories: row fins and loose fins.

The row of shark's fins, also known as abalone fins, skirt fins or group shark's fins, such as five-goat slices, green slices, toothpick fins, etc., are raised into shape, and some kind of shape-keeping method is adopted during the raising of shark's fins, so that the fins' needles are connected together through the soft periosteum. The good rows of wings are fan-shaped comb-shaped, complete shape, beautiful and generous.

Scattered shark's fins are made from thinner and smaller shark's fins, and the fin needles are separated into a fan-like shape.
