Huang Song-yuan, who is also president of the School Health Association of the R.O.C., says students going to the tea room to carry kettles of boiling water raises concerns about safety, whereas drinking water machines are not easy to maintain. "The filter should be cleaned once a week and changed every half year," he says. "How many schools can do this?"
兼任學校衛生學會理事長的黃松元指出，由同學到茶水房提水，安全堪慮，使用飲水機則維護不易，「濾心一星期要清洗一次、半年要換一次，有多少學校能做到？」
