Having a child studying at one of the schools with an average of 44 students per class, Mr. Tran Minh Dat (Cau Giay district, Hanoi ) expressed: "My child studies at a public primary school that is not high quality or a district-standard school, but due to the large population, the number of students from the surrounding area applying to study each year is also very large. The school is small, the children do not have space to play, there are no functional rooms. The children simply go to school, go to school and then go home. The desks and chairs are even placed close to the teacher's podium. Looking at my child's school and class, I feel so sorry for them."

With her child about to enter first grade, Ms. Nguyen Hai Anh (in Nam Tu Liem district, Hanoi) hopes: "Hearing that the Ministry of Education and Training requires primary schools to ensure a class size of 35 students, I hope schools will apply it seriously. First graders are still confused and need more tutoring from teachers, but in reality, the class is too crowded and the teacher cannot take care of the whole class. Parents like me are worried and anxious about sending my child to pre-primary school."

Ms. Le Thuc Hanh - a parent in Thanh Xuan district, Hanoi said: In grade 5, my daughter studied in a class with a total of 55 students, including 26 desks, so it was not possible to ensure 2 students per desk, some desks had 3 students, very cramped. There were days when she was afraid to go to school because the seats were too crowded, she was a girl but was seated between 2 tall boys, the desk was only about 1.2m long. The school bag was heavy, there was no place to put it, had to be put down at the feet, hindering walking and causing discomfort when sitting to study. There were not enough seats, making studying and writing difficult, leading to poor academic results for students, causing anxiety, especially in the hot late summer and early autumn weather.

Furthermore, according to Ms. Hanh, there are many students who are large, develop prematurely, and are obese. The cramped seating makes them irritable and quarrel with each other. The classroom is crowded with students, and the desks and chairs are placed close together, making it difficult for them to move around, during recess, or for the children sitting inside who want to go out to drink water or use the restroom. "I see that the children are overweight, the classroom is really overloaded," Ms. Hanh said.

Currently, Ms. Hanh's eldest daughter is in 7th grade, while her youngest son is still studying at the district's key school, so having a large class size is inevitable. Ms. Hanh hopes that schools will balance class sizes to ensure better teaching quality, and students will have space to study and experience because they spend more time living, playing and studying at school than at home.
