There is a tree that stands firm in a snowstorm, showing off its greenness. It is labeled as an evergreen, and is the symbol of integrity and firm spirit from old times, as it keeps the green color alone when everything changes. This is the pine.
It’s easy to think that the pine tree leaves never fall and stay on the branch all the year round because they seem always green. In autumn, however, pine tree leaves turn yellow and pile up under the trees. Then, how can the pine tree always stay green despite the fallen leaves?
Pine trees have new leaves every spring, and the leaves usually last for two years. That means the trees drop their old leaves and put forth new leaves every two years. When the spring leaves go through winter and are about to fall in the next autumn, newly sprouted leaves in that year are already fully grown. This is how pine trees stay green. It keeps budding and dropping old leaves. The secret of the pine tree is not unchangeability but constant change.
