Inside the caves of Mount Baigong, and in the surrounding area, there are dozens of strange pipe-like structures, subject to all sorts of conspiracy theories and rumors.
Known as Baigong Pipes, the first references to the structures appear to be from the Chinese state media affiliated news site Xinhua News Agency. According to the article, the pipes were made up of “30 percent ferric oxide [iron oxide] with a large amount of silicon dioxide and calcium oxide”, while 8 percent of the makeup of the pipes could not be identified by the scientists studying it.
