What is star feng shui? What is its content?

Star geomantic omen: a branch of geomantic omen, ancient emperors and nobles attached great importance to what happened after death and wanted to continue to enjoy the treatment they enjoyed before their death. Not only that, they also believe that the rise and fall of the world originated in Long Mai, so the mausoleum should be set in a treasure trove of geomantic omen. Yong Zhengdi once painted the outline of the mausoleum. He said: Gankun meets the land of Xiu Xiu, the place where Yin and Yang meet, the cave is full of sand and water, everything is beautiful, the situation is reasonable, the auspicious places are salty, and the mountains are in good order, so it is the land of Shangji.
