  We present new 1.5-8.5 GHz Very Long Baseline Array (VLBA) observations and
0.32-1.26 GHz Giant Meterwave Radio Telescope (GMRT) observations of
J0354-1340, which is the only known radio-quiet (RQ) or radio-intermediate (RI)
narrow-line Seyfert 1 galaxy with a 100-kpc two-sided radio jet. A pc-scale
one-sided jet in the southeast direction from the core emission is found in the
VLBA observations, while the kpc-scale jet observed with Karl G. Jansky Very
Large Array (VLA) and GMRT is in the south-north direction. The core spectra on
pc and kpc scales are presented in combination with the archival VLASS
observations at 3.0 GHz and the VLA C configuration observations at 5.5 GHz.
The pc-scale emission dominates the kpc-scale emission above ~ 5 GHz, and the
spectrum is inverted due to synchrotron self-absorption. This indicates a
compact synchrotron source with a size of ~ 0.04 pc, which is associated with
either the jet base or the corona. A sub-kpc scale jet, which is unresolved on
scales of ~ 3 arcsec, probably dominates the emission below ~ 5 GHz. Future
radio observations can explore the jet structure between the pc and 100 kpc
scales, the origin of their direction mismatch, and the pc-scale jet proper
motion. It remains to be explored how common such large-scale jets are in RQ or
RI AGN.
