  From 2011 to 2021, LAMOST has released a total of 76,167 quasar data. We try
to search for gravitationally lensed QSOs by limiting coordinate differences
and redshift differences of these QSOs. The name, brightness, spectrum,
photometry and other information of each QSO will be visually checked
carefully. Special attention should be paid to check whether there are groups
of galaxies, gravitationally lensed arcs, Einstein crosses, or Einstein rings
near the QSOs. Through careful selection, we select LAMOST J160603.01+290050.8
(A) and LAMOST J160602.81+290048.7 (B) as a candidate and perform an initial
analysis. The component A and B are 3.36 arc seconds apart and they display
blue during photometric observations. The redshift values of component A and B
are 0.2\% different, their Gaia$\_$g values are 1.3\% different, and their
ugriz values are 1.0\% or less different. For the spectra covering from 3,690
{\AA} to 9,100 {\AA}, the emission lines of C\,II, Mg, H\,$\gamma$, O\,III, and
H\,$\beta$ are present for both component A and B and the ratio of flux(B) to
flux(A) from LAMOST is basically a constant, around 2.2. We accidentally find a
galaxy group near the component A and B. If the center of dark matter in the
galaxy group is at the center between component A and B, the component A and B
are probably gravitationally lensed QSOs. We estimate that the Einstein mass is
1.46 $\times$ $10^{11}$ $M_{\odot}$ and the total mass of the lens is 1.34
$\times$ $10^{13}$ $M_{\odot}$. The deflection angle is 1.97 arc seconds at
positions A and B and the velocity dispersion is 261\,$km\,s^{-1}$.
Theoretically, this candidate could be a pair of fold images of a strong
lensing system by a galaxy group, and we will investigate the possibility when
the redshifts of nearby galaxies are available.
