The grandmother said, remember the old rules well:

1. A plump face naturally brings good fortune.

2. Men fear loneliness, women fear being alone.

3. Short and thick fingers lead to a busy life.

4. A long eyebrow is worth more than a thousand pounds of grain.

5. A man's broken palm weighs a thousand pounds, while a woman's broken palm leads to nurturing.

6. Fortunate people have hair on their legs, while unfortunate ones have hair on their legs.

7. A woman with her head up, a man with his head down, a water snake waist, a single garlic — these four people should not be looked at.

8. A hawk nose and eagle eyes should not be associated, a crooked neck can kill without a knife.

9. A turtle-backed snake waist should not be associated, a glance at a person can kill without a knife.

10. No flesh on the cheeks should not be associated, a face full of horizontal flesh is a fierce look.

Regarding these old rules, some believe they are part of traditional culture and have some truth; others feel they are feudal superstitions with no scientific basis. What do you think about this?
