  We report the discovery of a new stream (dubbed as Yangtze) detected in
$Gaia$ Data Release 3. The stream is at a heliocentric distance of $\sim$ 9.12
kpc and spans nearly 27$\deg$ by 1.9$\deg$ on sky. The colour-magnitude diagram
of Yangtze indicates a stellar population of Age $\sim$ 11 Gyr and [M/H] $\sim$
-0.7 dex. It has a number density of about 5.5 stars degree$^{-2}$ along with a
surface brightness of $\Sigma_G \simeq$ 34.9 mag arcsec$^{-2}$. The dynamics
and metallicity estimate suggest that Yangtze may be closely related to Palomar
1 and the Anticenter stream.
