My friend went to Africa to study abroad before. At that time, the photo that my friend had taught me that people in Africa draw an ethnic pattern on the skin for fashion that uses a unique ink called "Henna tattoo" A zebra came to my mind when I saw the beautiful lines. Zebras are born with beautiful stripes. We, humans, have no patterns on our skin. “Did humans come up with the Henna tattoos technique because they wanted beautiful decorations on their empty skin?”,I thought. On the contrary, if zebras’ stripe patterns looked like this Henna tattoo, it would be very neat.
