Diversification is the characteristic of Ms. Sofina Leung. When I pick up my son after class, I am always filled with pleasant amazement. Each time, I see different elements and materials, which set off and highlight the theme of the painting. But more importantly, it explores different angles from which children can look at their works and stimulate children's thinking. This process of  "re-examine -> introspection -> trying -> self-improvement" is the most important life's  lecture to children by Ms. Leung.
