Nails not only reflect a person's health condition but also reveal their personality and luck.

The ideal nail length is about half the length of the first finger joint. The crescent-shaped (white) area at the base of the nail should ideally occupy about one-fifth of the entire nail for auspicious signs.

Any damage or defects in the nails indicate early signs of illness; it is best to seek immediate medical diagnosis.

Standard nails signify good health, completeness, clarity, and straightforwardness. Such individuals are likely to gain affection and trust from society and possess the fortunate traits for limitless career advancement.

Long nails suggest an artistic temperament with poetic and imaginative qualities, yet they often come with a slightly introverted nature. However, these individuals tend to be prone to respiratory system disorders.

Short nails indicate a sharp mind and diligence, but also a shallow understanding, a tendency to make enemies easily, and a predisposition to heart disease. For women, this often indicates ovarian deficiencies and is considered a sign of lacking fertility luck.

Broad nails represent an open-minded personality, strong social skills, and a caring nature, but excessive self-confidence may lead to poor judgment regarding outcomes. Narrow nails suggest timidity, high vigilance, and difficulty completing tasks due to overly ambitious ideals.

Round nails denote a cheerful disposition, excellent interpersonal relationships, and strong social adaptability, though emotions may be unstable and inconsistent.

Slender and elongated nails belong to gentle idealists who are not always kind-hearted. For women, such nails often indicate a susceptibility to spinal diseases. Triangular nails—whether upright or inverted—are associated with mental and physical imbalance, strong rebelliousness, and intense suspicion.

Numerous vertical lines on the nails, especially when accompanied by small granules along the ridges, suggest gastrointestinal disturbances caused by nicotine addiction, although other causes may also contribute to digestive issues.

Irregularly uneven surfaces on the nail indicate a predisposition to intestinal prolapse. If there is one or two indentations on the nail surface, it suggests hemorrhoids.

Nails with numerous straight lines typically indicate a constitution prone to nervous exhaustion.

Complex, wrinkle-like patterns on the nails indicate that nervous exhaustion has already reached a severe stage.
