Black ancient tea is valuable. Black bone tea has extremely high ornamental value. It is deeply loved by the public when grown as a potted plant, especially when it is made into bonsai. It is natural and reasonable for black bone tea to be called the "King of Bonsai" in Guangdong, my country. Not only is the tree beautiful in shape, but it also remains evergreen all year round. Palm elm leaves are few and small and difficult to care for. Things are rare and valuable, so black ancient tea is valuable.
