But it also depends on the individual's calligraphy foundation. If you already have a certain basic knowledge of regular script, it will be relatively easy to learn official script, and it will take about 2 months to get started. However, if you don't have any foundation, it may take longer to master official script.
Therefore, the time to study official script will be different due to personal circumstances and teachers' teaching level. It is important to keep practicing every day and seek the correct guidance from the teacher in order to better master the skills of official script.
