The cypress tree is evergreen all the year round and has strong vitality, which should be very auspicious, but this kind of tree is often planted in the cemetery and is called the grave tree. Many people think that the meaning of planting cypress in yangzhai is unclear, so it is often regarded as a new species. The reason why cypress trees can't be planted at home is that cypress trees are planted in ancestral graves, and the mourning hall uses cypress leaf's thinking, but it's not because cypress trees are unlucky. On the contrary, cypress symbolizes long-term eternity.
