The "wai" is a traditional Thai gesture of greeting, respect, and gratitude. It involves pressing the palms together in a prayer-like position and bowing slightly. The height of the hands and the depth of the bow can vary depending on the social context and the status of the person being greeted. In Thai culture, the wai is an important part of social interactions and is often used when meeting someone, saying thank you, or showing respect. It is commonly seen in various settings, including temples and during ceremonies, reflecting the values of Thai culture and Buddhism.
