Abstract	The Belle and Belle II B-factories have collectively gathered an extensive 1.1~ab$^{-1}$ dataset of $e^+ e^-$ collisions at the $\Upsilon(4S)$ resonance, resulting in the production of numerous $B\bar{B}$ pairs. This allows for precise measurements of hadronic $B$ decays, which is essential to test Quantum Chromodynamics (QCD) and refine theoretical models. This also helps improve simulation accuracy. We present results for the B to hadronic decays such as $B^- \to D^0 \rho^-$, $B \to DK^{}K_{(s)}^{()(0)}$ and $B \to \pi^{0} \pi^{0}$. These decays provide deep insights into absolute branching fractions and angular distributions of decay products and help measure CKM elements.
