  The directed and elliptic flows of positively charged Kaon produced in
$^{58}_{28}$Ni + $^{58}_{28}$Ni reaction at incident kinetic energy 1.91 AGeV,
experimental data are released newly by V. Zinyuk,et.al. in Ref.[arXiv:
1403.1504v2 [nucl-ex] 8 Apr 2014], are reproduced by using the covariant kaon
dynamics. Our numerical results indicate qualitatively the Lorentz force is
necessary to explained reasonably the data as soon as the space-like part of
kaon's vector potential is involved. The sensitivity of $K^+$ directed as well
as differential directed flow on the Lorentz force are also observed near
target rapidity.
