There is an ancient saying of "one fate, two luck, three feng shui, four accumulation of yin virtue and five reading". Feng shui is one thing, and innate horoscopes are another, and the innate horoscopes have a greater impact on a person's life, far greater than the influence of feng shui.
Rich people live in luxury houses because they have it in their destiny, which means they have the right horoscope and can afford such a house (that is, they can afford wealth). As for ordinary people, most of them are better off living in smaller homes, so as to gather energy and wealth, they can get a better Feng Shui aura.
