  The rotation of sunspots of 2 yr in two different solar cycles is studied
with the data from the Helioseismic and Magnetic Imager on board the \it Solar
Dynamics Observatory \rm and the Michelson Doppler Imager instrument on board
the \it Solar and Heliospheric Observataory.\rm We choose the $\alpha$ sunspot
groups and the relatively large and stable sunspots of complex active regions
in our sample. In the year of 2003, the $\alpha$ sunspot groups and the
preceding sunspots tend to rotate counterclockwise and have positive magnetic
polarity in the northern hemisphere. In the southern hemisphere, the magnetic
polarity and rotational tendency of the $\alpha$ sunspot groups and the
preceding sunspots are opposite to the northern hemisphere. The average
rotational speed of these sunspots in 2003 is about $0^{\circ}.65 \rm \
hr^{-1}$. From 2014 January to 2015 February, the $\alpha$ sunspot groups and
the preceding sunspots tend to rotate clockwise and have negative magnetic
polarity in the northern hemisphere. The patterns of rotation and magnetic
polarity of the southern hemisphere are also opposite to those of the northern
hemisphere. The average rotational speed of these sunspots in 2014/2015 is
about $1^{\circ}.49 \rm \ hr^{-1}$. The rotation of the relatively large and
stable preceding sunspots and that of the $\alpha$ sunspot groups located in
the same hemisphere have opposite rotational direction in 2003 and 2014/2015.
