Dragon tattoos can represent a lot of different things. Some people might think of them as being brave, strong, and powerful. Warriors in many places had dragons on their armour or painted them on their flags. Today, dragon tattoos are usually seen as protective or spiritual symbols protecting the person who wears them from harm.
The Chinese zodiac sign is another way to look at the dragon tattoo. If you were born in the year of the dragon, you are probably a natural leader who is ambitious, doesn't mind a challenge, and makes up your own rules.
