❍ 那位老人常告诫他的儿子们，勿“～”。他指出：一知半解会铸成大错的。The old man often told his sons not to “strike the copper basin and feel the candle to find out the shape of the sun”，as he pointed out that half-baked knowledge would lead to great blunders. 扣盘扪烛盘（槃）kòu pán mén zhú扣：敲击；扪：抚摸。比喻认识有片面性，没有把握要领和本质。know superficially, take a one-sided approach to problems, one’s limited understanding |
