Abstract: The Belle II experiment started its physics run in 2019 and has accumulated more than 213.49/fb heretofore, and aims to accumulate more than 50/ab until the end of the experiment. Based on the latest BelleII Monte Carlo simulation dataset, this thesis delve into the strategy to search for CP violation effect in the 𝐷0 → 𝜋+𝜋− and 𝐷0 → 𝐾+𝐾− channels in order to perform the real data analysis by adopting the 𝐷∗+ tagging method which have been used from Belle experiment. The event selection and fitting procedures to obtain the preliminary result will be discussed, while thoroughly investigating the accuracy and usability of the 𝐷∗+ tagging method
