Recently someone is spreading the unfounded information that Xuan Kong Fei Xing 玄空飞星is a school that started around 1930. His intention is to say that this relatively new school of Feng Shui does not work as some masters claim and that his practices are much more powerful. This is very poor marketing exposing his ignorance.
Probably this person can speak but not read and write in Chinese. The principles of Xuan Kong begins with the Qing Nang Jing 青囊经 given to Zhang Liang 张良 by Huang Shi Gong 黄石公 during the reign of Qin Shi Huang 秦始皇 (259 BC - 210 BC). The technique of the flying stars is well explained in the classics Xuan Kong Mi Zhi 玄空秘旨，Xuan Ji Fu 玄机赋, Fei Xing Fu 飞星赋 all published in the Song Dynasty 宋朝 (960-1279).
