This illustration gives us two pieces of information. First, the purpose of engraving the whole map of Wutai Mountain is to worship the scenic spots with thorns and visit the "four good people" of Wutai Mountain. At the same time, it can spread the scenery for future generations to learn, which is similar or the same as many other words or pictures. Secondly, the author of this print is "Sangamah Ming Ge Long Long Zhu".
At present, the National Library of China also has two maps named "Complete Map of Wutai Mountain". According to the records in Yu Tu Lu, one was recorded during the Tongzhi period, without an author, and the other was "made in the twenty-sixth year of Daoguang", and the author was "Dragon". By observing the maps of the so-called Tongzhi period, the author finds that there are no notes such as "Wutai Mountain Sacred Land Poetry" under the map in the Library of Congress, and there is no signature and time, but the contents of the two maps are very similar, and it is very likely that they were redrawn according to Daoguang block print.
I haven't had a chance to watch the other one yet, but the time and the author's point of view are very similar. At present, there is an engraving of Wutai Mountain Holy Land in Cifu Temple, which is said to have been engraved with the name of Lama Sanger in the twenty-sixth year of Daoguang. Cha "Long Ge" is a taboo name for monks in Tibetan Buddhism, and it is often used as a self-declaration. Therefore, the names of Long Ge Dragon Ball and Lama Sangamah should refer to the same person, which may be the difference between self-declaration and him. It can be speculated that the sacred land map of Wutai Mountain collected by the National Library of Daoguang for twenty-six years and the Library of Congress of the United States probably originated from this block print of Cifu Temple. ?
