Slip-skin mandarins are evergreen small trees, a newly bred variety of golden oranges in China, bred from common mandarins. Each fruit weighs 12-15 grams, with the fruit weighing 20 grams, ripening in November and turning a bright orange-yellow at maturity.

The smooth skin mandarin oranges have a glossy peel with sparse oil glands and no pungent, spicy taste. They can be eaten with the skin on, offering a crisp peel and sweet flesh. The fruit contains 19%-22% soluble solids and has a total sugar content of 15%-18%.

Slip-skin mandarins bear fruit early and in abundance. Young trees planted can bloom and fruit in the same year, with an average yield of about 2.5 kg per tree in the second year. By the third year, the yield can reach 8 kg per tree, and mature trees can produce over 25 kg per tree. The price at the origin is around 10 yuan per kilogram, offering a high economic return.
