Which of the following is characteristic of a yang sign?

A yang sign in Traditional Chinese Medicine (TCM) is typically associated with an abundance of energy, warmth, and activity. Individuals exhibiting a yang sign often have a preference for activities that align with these characteristics. Lying stretched out can be indicative of a yang disposition because it suggests a desire to expand and occupy space, reflecting the active and assertive nature of yang energy.

In contrast, lingering disease, gradual onset, and chronic disease are typically linked to yin or deficient conditions, characterized by the manifestations of stagnation or insufficiency. These conditions do not resonate with the vitality and expansiveness that define yang signs. Therefore, the preference for lying stretched out aligns with the energetic and lively attributes of yang, making it the most suitable characteristic associated with this concept in TCM.
