Ying-spring (water) point.

bubble_chart Etymology

The point is located on ulnar side of dorsum of hand, between 4th and 5th fingers. When making a fist, this area resembles armpit ("Ye", 腋) of a person, with the two sides resembling gates ("men", 門), hence the name. Historically, the terms 液 (ye, fluid), 腋 (ye, armpit), and 掖 (ye, to support) were used interchangeably due to their identical pronunciation. (Lingshu, SuwenWang Bing's note, and Tongren Shuxue Zhenjiu Tujing use "液", Zhenjiu Jiayi Jing uses "腋", Huangdi Neijing Taisu and Qianjin Yaofang‧ use "掖").
