Abstract: The explanations of "metal post holding dew" in Tu Fu’s poems,have been all wrong since the ancient times.The "metal post holding dew" refers to the copper post "Tianshu" which was constructed in the Wu Zetian period.From the scale,the copper post is the same as the "metal post with holding dew plate" constructed by Emperor Wu Di of the Han Dynasty.The poet Li Qiao in the early Tang Dynasty called it "metal post with holding dew" plate,and Tu Fu called it "metal post holding dew" following him.
