4. Cultural Background and Notes

• This idiom originates from the biography of Su Weidao (苏味道) in the Old Book of Tang (旧唐书). Su Weidao was a high-ranking official who was terrified of making mistakes and being held responsible. He famously said that one should not make clear decisions but should instead 'rub the edges' (模棱) and hold both ends so that one can adapt to any outcome.
• Because of this philosophy, Su Weidao was mockingly nicknamed 'Su Moleng' (苏模棱), or 'Su the Edge-Rubber.' Today, the phrase remains a strong criticism of 'playing it safe' at the expense of truth or efficiency.
