Which LU point lies on the lateral aspect of the chest, in the first intercostal space, 6 cun lateral to the midline, 1 cun inferior to Yúnmén?

• A. LU-1
• B. LU-2
• C. LU-3
• D. LU-4

Answer: (A)

This question tests exact chest-point location on the Lung meridian. The description points to Zhongfu, the point located on the lateral chest in the first intercostal space, about 6 cun from the midline, and exactly 1 cun below Yunmen. Yunmen is LU-2, which sits in the second intercostal space; being 1 cun inferior to Yunmen places you in the first intercostal space, at the 6-cun lateral position from the midline. That precise positioning matches Zhongfu, making it the correct choice.
