Can geomantic omen cure diseases?

Teacher Xuan Yi talked about this problem in class. Not all diseases can be cured by the regulation of Feng Shui. If it is a disease caused by pure geomantic omen, it can be cured through the adjustment of geomantic omen. If it is not a disease caused by geomantic omen, it can be slightly improved through the adjustment of geomantic omen, but it still needs medical treatment, medicine, injection and surgery.
