Pine bonsai are ancient and long-lived; the saying "fortune as vast as the East Sea, longevity as enduring as the southern mountains" refers to exactly this.

Bonsai: "Fortune as vast as the East Sea's ever-flowing waters, longevity as enduring as the southern mountains' unaging pine" - this speaks of the pine's great age!
The pine is the chief of all trees. It endures barren soil and can grow in shaded cracks among dead rocks (as the strange pines of Huangshan prove). It defies frost and snow, staying green through all four seasons without withering, symbolizing constancy and eternity.
Through the ages, countless people of aspiration and letters have praised the pine in song and celebrated it in poetry. They praise the pine's solemn dignity and towering pride; they celebrate how it endures cold without decline and stays green through all four seasons.
There is proof in the Song dynasty poem "Ancient Pine at Jinglin Temple" by Zhong Jiao: "Ancient pine, ancient pine, growing on the ancient road; its branches bear no leaves, its bark bears grass. Travelers did not see when the tree was planted; how many times has the tree seen travelers grow old?"
The pine is the longest-lived tree species in the world, enjoying a lifespan of ten thousand years. As the saying goes: a thousand-year turtle, a ten-thousand-year pine. In our country's folk customs, birthday congratulations often include the phrase "fortune as vast as the East Sea's ever-flowing waters, longevity as enduring as the southern mountains' unaging pine."
