Introduction to the ancient ginkgo tree: The ancient ginkgo tree in Zifang Temple is 500 years old and stands in perfect contrast to Zifang Temple. Tongbai Mountain is the secluded place of Zhang Liang, a famous official in the Han Dynasty. According to the "Book of Han. Zhang Liang": Zhang Liang assisted Han Emperor Gaozu to unify the world. He became ill due to overwork and became weak and sick. In order to seek longevity and purity, he secluded himself in the mountains and rivers. So he traveled all over the world. He found a natural cave on the main peak of Taibaiding to live in seclusion and cultivate himself, so the cave was named Zhangliang Cave. There is also a Zifang Temple in the Taibaiding Scenic Area of Tongbai Mountain in Suizhou, which has been popular since ancient times.
