bubble_chart Etymology

In ancient times, "Xuanji" (璇璣) referred to an astronomical instrument used for measuring stars. Later, it came to represent the four stars of the Big Dipper's "Dipper Bowl," which are opposite the Purple Palace constellation. The acupoint is located above Zigong (CV19) and functions to ventilate and regulate lung qi, hence the name.
