To convey the idea of "good" as in the expression "good work," you would place your palm against your stomach, rubbing in a circular motion.

In the expression "good work," the typical gesture to convey the idea of "good" involves placing one hand over the heart or using an approving signal, such as a thumbs-up. Rubbing the palm against the stomach in a circular motion does not conventionally symbolize "good" in most cultures and may not be recognized or understood in that context. This misunderstanding reflects that gestures can have specific meanings based on cultural norms, and the described motion isn't widely associated with an affirmation or approval of work. Thus, the statement is false, as the gesture does not align with the established representation of "good."
