The wealth corner of your house is usually 45 degrees from the entrance of the door. For the living room, it is 45 degrees from your main door. This is the primary wealth corner (正财位) which can be used to increase the wealth luck for everyone living in the house, especially in their career or business. The wealth corner where most "Qi" is kept in the house. The more "Qi" you can keep in your house, the richer you will be.
However, not all wealth corners of the house can qualify for Feng Shui wealth corners. A good Feng Shui wealth corner is made up of two panels of walls with no windows. If one of the walls has windows, full-length windows or balcony glass doors, it cannot be considered as a wealth corner. If there is an air conditional installed at the corner, it cannot be considered as a wealth corner either.
If you are unable to find a good wealth corner in your living room, it is likely that you have difficulties in accumulating wealth. But, that's not the end of the world. You can still find secondary wealth corners (次财位) which are not 45 degrees to your main door or place some Feng Shui cures to save your wealth corners. I will share more on what are the cures when you don't have a primary wealth corner. Stay tuned.
