Wyvern is a kind of Warcraft in Western legends. Its body is like a dragon and small, with only two feet, claws and toes like birds, wings covered with scales or feathers, and tail barbs or serpentine. Wyvern is descended from dragons and Griffins and can attack threatening enemies with their sharp claws and teeth.

Generally speaking, Wyvern can attack with venom, but can’t spit fire. Due to their relatively thin physique, they usually like to hunt herdsmen’s sheep. Wyvern doesn’t have a strong sense of territory and likes to live in caves on the top of the mountain. Compared with quadruped dragons, Wyvern tends to be smaller, more smelly and have a lower IQ. In fact, in the eyes of dragons, Wyvern is actually a much lower creature than them.

The Chinese dragon tattoo symbolizes a spirit and is the totem of a nation. It is of great significance. It can be said that it is a general term of a nation and a general term of a region. It has a long-standing sense of inheritance. In Chinese traditional culture, the dragon is not only a symbol of power, nobility and honor, but also a symbol of luck and success.

The reason why the Chinese dragon tattoo has this cultural symbolic significance is closely related to the incomparable magic power of the dragon in legends and myths, such as flying clouds and fog in the sky, chasing waves and waves in the sea, and calling the wind and rain in the world. But more importantly, it has often become the “exclusive patent” of Chinese slaves and the supreme ruler of feudal society for thousands of years, which is synonymous with imperial power.

Probably in the Kamakura period of the 12th century, Zen spread across the sea to Japan, which had a great impact on Japan’s religion, culture, art and even national character.

However, as the founder of Zen Buddhism, Dharma walked into thousands of households in Japan with the image of a tumbler of Wanda in the hundreds of years of Edo era. This bearded, no hands, no feet, no eyes “Daruma doll” is very popular among Japanese people, among which takazaki City, Gunma prefecture is the most famous.
