True or False: Yin (zang) organs are hollow?

The statement that Yin (zang) organs are hollow is false. In Traditional Chinese Medicine (TCM), Yin organs, also known as zang organs, are characterized by being solid in nature. They include the heart, liver, spleen, lungs, and kidneys, all of which play vital roles in storing essential substances like blood, Qi, and essence.

These organs are associated with the storage and processing of vital substances, contrasting with Yang (fu) organs, which are hollow and involved in transportation and digestion. Understanding this distinction is fundamental in TCM, as it influences diagnosis and treatment strategies. Hence, the characterization of Yin organs as hollow does not align with the established principles of TCM regarding organ functionality and structure.
