Here is a real case done on a client whom has requested me not to disclose.
This client is a public listed company whom had ventured into property development as part of their diversification plan. The old show room had problems attracting walk in viewers not to mention customer. After the feng shui audit, a date was selected for the re-opening of the show room. The re-opened show room had very good response to the point they have to limit the promotion since they were listed as a different section of the market and property development is their second business so to speak.
Thus when a proper date is selected, results comes fast and good. This is just one of the many cases when a good date is selected.
