Explaining the benefits of placing a dish of lemon and salt in an air-conditioned room, Doctor and Master Vũ Quốc Trung shared that the air inside air-conditioned rooms is often dry and lacks proper circulation. Therefore, placing a lemon containing essential oils with a pleasant scent, combined with salt, helps relax the nerves, reduce anxiety and stress, and effectively repel insects. This significantly improves the quality of sleep and enhances one's mood, increasing focus and work efficiency.

Aside from purifying the air and promoting better health, this practice has three important, lesser-known benefits in feng shui:

1. Changing Your Luck
   If you feel your luck has taken a downturn, it could mean that a lot of negative energy has accumulated around you. If not removed soon, it will continue to decline. To dispel this bad energy, try placing three lemons cut into four parts each on a plate, sprinkle a bit of salt over them, and place the dish near your bed.

2. Driving Away Misfortune
   There's a reason why our ancestors had the tradition of scattering salt outside after offering prayers. According to my research, salt has the power to dispel bad luck, ward off evil, and cleanse the surrounding space while attracting wealth. Meanwhile, lemons are effective in removing and neutralizing sources of negative energy. Combining these two helps purify the living space and creates positive energy, allowing everything to flow smoothly and successfully. By following this guide, you’ll soon experience unexpected luck and fortune.
