Huanro
A type of Róuyīn 揉音.
Same as jirou but twice as long. Pluck a string then press it quickly several times with the left hand raising its pitch to the next note on each press. Kwok writes that huanrou is generally used on a note of two beat's duration, usually at a relatively slow tempo, and contains about three presses. Rhythm and number of presses vary according to personal taste.
