Dok ma kuea or pea eggplant flowers, represent modesty. When the flowers are fully grown, the blossoms face downwards toward the ground. That represents the way that students should gently take a bow or modestly show respect to their teachers.
DISCIPLINARY LESSON
Kao tok, or popped rice, is made from rice grains that have been softened by being soaked in water for many hours. The rice is later roasted until the white rice grains inside poke out of the chaff.
Symbolically, the rice grains represent students, while the water refers to the gentleness of teachers. The process of roasting represents the strict discipline that teachers also sometimes need to enforce.
