Although no one knows how the tree has survived through harsh temperatures and typhoons, it has grown steadily. Its green canopy has seen generations of bathers, from childhood to old age, coming and going. Once the largest beach in Asia, the stretch of sand can accommodate tens of thousands of people.

During the rehabilitation of beach in 1984, about 20 Japanese black pines were planted. Only one survived a ferocious typhoon the following year. Japanese black pines were first imported to Qingdao in 1901, and were usually planted on the hills, along the coasts, and in parks.

In the summer of 2004, to protect the tree, the beach authorities fenced off the area around it. Since then it has thrived.
