One press: relax the natural duvet, let it recover naturally for three minutes, then press the quilt by hand, then release the hand, if you can quickly rebound to restore the original shape, it is the best. The faster the rebound speed, the better the down quality. If it is not elastic at all, the filler is likely to be chicken feathers or other long-haired pieces.

Two touches: use the touch to test the softness of the hand, whether there are complete small pieces or too large and thick long hair pieces, feather tubes and so on. If the hand feels soft and complete, the small pieces are authentic products.

Three beats: Strike hard on the quilt to see if there is any dust spillage. The less the dust spill, the better.

Four rou: Use your hands to quilt the quilt. If you have a plush, it means that the fabric is velvet. It is not suitable for purchase.

Five smells: Close to the duvet for a few deep breaths, no smell is good.

Six nian: Use a hand to rub the weight of a duvet, while watching the size of the volume, the lighter the weight, the bigger the better.
