When ionized by a quasar, these gas flows can be directly traced as giant nebulae. We present a study of a giant nebula around a radio-loud quasar, 3C$\\,$57 at $z\\approx0.672$. Observations from MUSE reveal that the nebula is elongated with a major axis of $70 \\, \\rm kpc$ and a minor axis of $40 \\, \\rm kpc$. The nebula displays an approximately symmetric blueshifted-redshifted pattern along the major axis and multi-component emission features in its $\\rm[O\\,II]$ and $\\rm [O\\,III]$ profiles.
