The passage describes a special class for disabled children taught by a young teacher named Pham Thu Thuy. Initially, only five children attended due to opposition from parents who believed their children could not learn. However, the teacher made great efforts to help the students, such as demonstrating how to add and subtract using hand gestures during a math lesson. Her dedication was time-consuming but effective, as the children began to learn and feel proud of their accomplishments. The teacher opened a new world of learning for students who come from poor families and face disabilities.
