Large nostrils mean

Large nostrils mean that the person will suffer a loss caused by external causes before any major achievement

A person's inability to accumulate wealth...that's why

 People with large nostrils should not hold movable property but immovable property.

If a person has open nostrils with a point between the eyes, a point at the top of the nose, a point in the middle of the nose, and a normal tip of the nose...he still has a chance to enjoy success.
