The foundation classes provide an extensive body of knowledge about the human body, enabling learners to understand the origins of variations in physical appearance as well as how to apply this knowledge to artistic practice and to various other fields such as aesthetics, fashion, and design. In Hanoi, each foundation class is conducted over a period of 8 weeks, while in Ho Chi Minh City it is condensed into a one-week format. The class includes a structured homework system along with objective and precise evaluation criteria. In addition, students are encouraged to propose their own exercises tailored to their individual needs. Overall, the foundation class reflects the spirit of the discipline: practice focuses exclusively on the use of ballpoint pens or ink pens, without the use of pencils, in order to ensure the fastest possible progress within the shortest amount of time.
