出卦

There are various types of fengshui luopans 罗盘; San-he pai 三合派 (3 combinations), san-yuan pai 三元派, xuan kong da gua 玄空大卦 and etc. Some masters even designed their own luopans， they combined the various school of thoughts together to form a luopan just to suit their needs.

Luopan is basically just a compass except that it has additional information which cannot be found in normal compass. Information such as 24 mountains二十四山, 64 guas 六十四卦, early heaven trigram 先天卦 and later heaven trigram 后天卦. Some luopans can house more information that are not stated here.
