  We present detections of stellar flares of Wolf\,359, an M6.5 dwarf in the
solar neighborhood (2.41~pc) known to be prone to flares due to surface
magnetic activity. The observations were carried out from 2020 April 23 to 29
with a 1-m and a 0.5-m telescope separated by nearly 300~km in Xinjiang, China.
In 27~hr of photometric monitoring, a total of 13 optical flares were detected,
each with a total energy of $\gtrsim 5 \times 10^{29}$~erg. The measured event
rate of about once every two hours is consistent with those reported previously
in radio, X-ray and optical wavelengths for this star. One such flare, detected
by both telescopes on 26 April, was an energetic event with a released energy
of nearly $10^{33}$~erg. The two-telescope lightcurves of this major event
sampled at different cadences and exposure timings enabled us to better
estimate the intrinsic flare profile, which reached a peak of up to 1.6 times
the stellar quiescent brightness, that otherwise would have been underestimated
in the observed flare amplitudes of about $0.4$ and $0.8$, respectively, with
single telescopes alone. The compromise between fast sampling so as to resolve
a flare profile versus a longer integration time for higher photometric
signal-to-noise provides a useful guidance in the experimental design of future
flare observations.
