Cypress is brave, strong and tall in the cold snow, which is the length of a hundred trees and will always be a symbol of justice, nobility, longevity and immortality. Cypress is an emotional carrier of sadness and mourning abroad, so cypress always appears in the cemetery. Coffins in ancient Rome were usually made of cypress trees. Greeks and Romans used to put cypress branches in the coffins of the dead. China people planted cypress trees on the graves and graves of the deceased in order to let them "sleep in peace". Cyperaceae, whose scientific name is cypress, comes from Zyparissias. In Greek mythology, there was a boy named Separis who liked riding horses and hunting. He was heartbroken when he shot a deer by mistake while hunting. So eros, the god of love, suggested that the general god should turn cypress into cypress, so that he would not die, and he would be sad for life. The name of cypress evolved from the name of a teenager, and cypress became a symbol of sadness and mourning.
