Pine and cypress trees were originally trees growing in cold zones and mountains. Due to their long-term life in cold environment, they have formed a unique cold resistant structure. The leaves of pine and cypress trees are generally reduced in needle shape, linear or scale shape. Due to the small leaf area, water is not easy to evaporate and lose. Some leaves have thick cutin or wax, and some have thick villi. If you take a pine needle and observe it carefully, you can see that there are dense white fluff on it, which feels very smooth when touching,
