Pure natural honey can be divided into mature natural honey and immature natural honey. Mature natural honey is nectar collected by bees, which is heated, fanned and drained by bees. When the water content is below 20%, bees seal it with wax, which is also called honey sealing. The natural honey of Xiao Wu's family in Zhangjiajie basically has no water, and the honey concentration is very high. This kind of honey will be as beautiful as pine flowers after crystallization. As long as it is sealed, it will not deteriorate for ten years, but some honey will deepen in color.
