Few days ago, my son asked me which primary school in Hong Kong is the best. I carefully asked him why he wanted to know. He said some other children discussed this issue in the playground. I then told him there is no definite answer. A school is good or not depends on (1) whether you are happy in the school; (2) whether you enjoy the school life; (3) whether you can learn something at the school. If the answer to all questions is positive, then you are studying in a good school. He is satisfied that he is now in the best school, in his point of view.
