Introduction to Magnolia officinalis: There are several precious ancient trees in the Tianhou Palace. The two male and female ginkgo trees in front of the main hall are old things from the Ming Dynasty and are more than 500 years old. The tree is covered with red silk threads and prayer kits, its branches are curved, and the ground is covered with thick shade. The arborvitae next to the mountain gate is estimated by experts to be more than 300 years old. Coincidentally, there is a magnolia tree in front of the Temple of Wealth that is over 100 years old. Ginkgo is the same age as Tianhou Temple, and this Magnolia officinalis tree was built around the same time as Qingdao.
