The south is a fire, so you can consider sitting south facing north when placing tables and chairs. In addition, red is also fire, so you can add more red decorations or wear red clothes and accessories. Choose the name of the company or commodity next to the word "fire", such as "Yan", or directly use "fire" and "South". In addition, choosing a number with more numbers 2 and 7, or choosing the house number and floor of 2 and 7, also has a certain effect.
Although the fire can be supplemented from the perspective of geomantic omen, it is human factors and its strength is limited. If you want to be lucky, healthy and smooth, you should do more good things and not do bad things. This is the fundamental way. For reference only, I hope it will help you.
