Totally different. The duvets of this brand are made of duvets (for example, 90% duck down refers to duvets from the neck to the abdomen of ducks, which can be soaked in water at ordinary times and have the best warmth retention, without down, accounting for 90% of the stuffing in the quilt); In fact, velvet silk is not of great value and has poor warmth retention. Most of them are called flying silk in the industry, small and scattered. Don't buy it. Professional duvet manufacturers include Zhejiang Sanhong Group, Anhui Hongrun Group, North Swan Company Limited and Zhejiang Qiao Liu Down Company Limited.
