Among them, there is also a fragrant bag to grasp the week. Put all kinds of spices and herbs in the beautifully made sachets, so that the baby can feel happy and at ease because of smelling the fragrance. To some extent, sachets also perceive children's interests and potential through fragrance.

Ancient sachets were made by women or women, and the materials were mostly beads, silk, herbs and various petals. The sachet is not only used to grasp the week, but also a very popular ornament for women in daily life.
