What are the rules for robbing a tomb?

There are seven main aspects in the geomantic survey of cemeteries, namely, searching for dragons and acupoints, dividing gold vertically, choosing the right time and day, breaking ground and opening holes, orienting urns, erecting tombstones and leaving graves.
