According to your description, the gate faces south, which is a good direction, because the south belongs to fire and can bring warmth and vitality. However, the middle of the gate is facing the roof outlet of the previous family, which may affect the wealth and career of the family. The water outlet is the place where family belongings flow out. If the water outlet is facing the gate, it may lead to "unfavorable water outlet" and affect family wealth and career.
In addition, the west wall of the south house faces the alley mouth, which may lead to "road rush", that is, the road leads directly to the house, which will also affect the wealth and safety of the family. If the alley mouth leads directly to the door or window of the south house, the impact will be more obvious.
To sum up, I suggest you consider setting some barriers at the door or window, such as screens, plants or mascots. , in order to resolve the adverse effects. At the same time, you can also pay more attention to the internal layout of the house, such as putting the bedside, desk and stove in an auspicious position to increase the auspiciousness and vitality of the home.
