Motivated by a recent work of Chen–Zheng (J Geom Anal 32:141, 2022) on Strominger space forms, we prove that a compact Hermitian surface with pointwise constant holomorphic sectional curvature with respect to a Gauduchon connection (nabla ^t ) is either Kähler, or an isosceles Hopf surface with an admissible metric and (t=-1) or (t=3). In particular, a compact Hermitian surface with pointwise constant Lichnerowicz holomorphic sectional curvature is Kähler. We further generalize the result to the case for the two-parameter canonical connections introduced by Zhao–Zheng (On Gauduchon Kähler-like manifolds. ArXiv: 2108.08181), which extends a previous result by Apostolov–Davidov–Muškarov (Trans Am Math Soc 348:3051–3063, 1996).
