What feng shui procedures are required for the opening of factories and mines? Such as firecrackers and sacrifices.

First choose the opening date, and the time is the cutting time. For example, 9: 10 is auspicious time, so this time is the time to cut the ribbon. You can fire the gun during the ceremony, or you can end the ceremony.

Secondly, choose the day to break ground. It was then that firecrackers were set off.
