To allow children to learn in a comfortable and safe environment, the school has hired a professional cleaning company to carry out comprehensive cleaning and formaldehyde removal antibacterial disinfection services in the school before the start of the school year. However, some parents recently reported that they are worrying about the air quality in the school. Our school therefore had invited professionals in the field to carry out formaldehyde testing in our school on February 20, and we are pleased to share with you that the result showed that the reading was zero. Parents, please rest assured.
