Wearing dogwood is one of the traditional customs in China. Every September 9th, the Double Ninth Festival, I climb the mountain with a cloth bag on my arm and dogwood on it. Because Wang Wei's famous poem:
As a stranger in a foreign land,
Please think twice about your relatives during the festival.
Know where the brothers climb,
There is one person missing from the dogwood.
Therefore, Cornus officinalis is associated with relatives who miss him.
