Pō cì zhǐ 泼刺指 (trad. 潑刺指) Or Pō lá zhǐ 泼剌指 (trad. 潑剌指)

Sweep the index, middle, and ring fingers across two strings, twice. The first sweep is played away from the performer. The second is played toward the performer. The three fingers are held tightly together so they strike the strings simultaneously. The strikes are often followed by a dampening of the strings with the palm of the right hand, called fú 伏.

Ferguson says 泼刺指 (trad. 潑刺指) Pō cì zhǐ is two distinct actions: Pō and cì. I assume pō refers to the three fingers sweeping towards the performer while cì is when the fingers sweep away. However, Ferguson does not specify how much of this technique is included in that. Do the number of strings played at once matter? As It's unclear where the boundaries lie I have not given pō and cì their own entries.
