Some children may answer this way: cow tail northwest. This is wrong, and it is unknowingly wrong. Why is it wrong? The reason is “wrong direction”. In fact, the direction of Ngau Tau and the direction of the cattle has nothing to do, no matter where the Ngau Tau, cattle tail is generally downward. There are similar situations in mathematics learning, some questions
