From the perspective of geomantic omen, from which angle should demolition and foundation laying begin first?

If you demolish and rebuild on the original site, you need to choose two days. Because demolition and new construction are two different purposes, the method and the selected date are different.

Demolition of a house requires a broken date, which is destructive. Laying the foundation belongs to new construction, and what needs to be considered is to supplement the dragon, rely on the mountain and support each other. If dismantled in order, you can start from the white tiger position; If you lay a good foundation, you can start from Kyrgyzstan in the direction of sitting. If you are not sure, you can start with Qinglong on the left.
