The internal structures of pulsating white dwarfs can be explored only with asteroseismology. Time series photometric observations were made for the pulsating DA white dwarf (ZZ Ceti star) WD~0246+326 during 9 nights in 2014 with a bi-site observation campaign. Eleven frequencies were detected including 1 triplet, 2 doublets, and 4 single modes, which are identified as either $l=1$ or $l=2$ modes with the complementarity of frequencies present in the literature. From the multiplets, the rotation period of astrobj{WD~0246+326} is derived as $3.78pm 0.11$ days. The average period spacing of the l=1 modes $Delta P=29.3pm 0.2s$, implies that astrobj{WD~0246+326} may be a massive ZZ Ceti star concerning the $Delta P-M_*$ relationship for the DAVs. Preliminary analysis derives the stellar parameters of $M_*=0.98pm0.01$~${rm M_odot}$ and $T_{rm eff}=11700pm100$~K by fitting the theoretical frequencies of the eigen modes to the observed ones.
