The people of Thailand have in their nature the simple and natural smile of the various ethnicities. One of the ethnic groups uses bronze rings worn by women of the Kayan tribe. These utensils are placed on the neck, wrists and ankles as protection from tiger attacks. The placement is only done on women in the community because they are the center of life. Also the smile of connection with animals, so strong as if it were family. A sincere smile in everyday life.
