There are other designs such as the lion (Singhto), which is a symbolisation of bravery and cunning. Tai men would choose a individual design, not just a picture of a individual but tattoo their embody to look like tiger, many have had designs that awninged every square inches of their body. The reason for the individual organisation is that Tai people, especially the Lanna, believed that their ancestors were once tiger, therefore to show respect and in remembrance of their ancestors, they’d choose the individual design. Another favourite one is the hanuman, which is the Hindu monkey god, which is to protect against illness, against existence shot, against existence cut, and to give courage.
In part of the video where the men have strange reaction, it is believed that the unnameable designs that were tattooed (Sak) into their body, whether it be the tiger, dragon, or hanuman would become discover and they’d act like the animal that they chose, and this is a sign that that mortal truly gained the power of protection. Sak Yant is very fascinating to me; to the Thais, Laotians, Khmers, and many others, tattoo is not just a embody art but also a unnameable design.
