In this work, we construct six examples of conformal minimal two-spheres surfaces with constant curvatures of 4/7, 4/19, and 4/27 by the twistor map π:CP7→HP3. By the twistor map, we know that the horizontal minimal surfaces in CP2n+1 are equivalent to the minimal surfaces in HPn, and many conclusions about conformal minimal two-spheres with constant curvatures in CPn have been given. Based on Bolton's conclusion and Chen's general method to construct conformal minimal two-spheres, we get some conformal minimal two-sphere surfaces in HP3.
