  We present narrow-band images and long-slit echelle spectra of the planetary
nebula (PN) NGC 6778. The data show this PN as bipolar, with a very prominent
low-excitation equatorial toroid, high-excitation lobes and two pairs of
collimated outflows. Morphologically, the pairs of outflows are different from
each other; one is linear and oriented along the bipolar axis, the other
presents an S-shape with changing orientations. Besides the different
morphology, both pairs of collimated outflows present radial velocities
increasing with distance from the central star and share a common origin in
bright knots at the tips of the shell.
