The plaque "Yunya Chu Chu" was presented by the common people of Donghu County, Yichang Prefecture, Hubei Province in the 24th year of the Qianlong reign of the Qing Dynasty. It is impossible to verify who the calligraphy originated from, but judging from the size, texture and calligraphy taste of the plaque, it is by no means an ordinary person. The content has a double entendre: First, it implies that the young Zhenwu began his cultivation here. At the same time, it implies the emotions of the person presenting the plaque during his first visit to Wudang Mountain, revealing a desire to "come again". This plaque is an invitation for the renovation of the main hall by Emperor Qianlong of the Qing Dynasty. According to historical records, the main hall was renovated once during the 20th to 26th years of the Qianlong reign. Only at this time did the person presenting the plaque have the opportunity to present it and ascend to the grand hall.
