Chinese are relatively polite to outsiders, no matter what they may feel inside. On the other hand, when I ask them to adopt a stance of blame, many people can't bring themselves to point their finger at someone else. Many students even find it difficult to say the word "no" to others.
我在工作坊教學時注意到，中國的學員比較容易了解討好的姿態，對外人都比較有禮貌，不管內心感受如何，甚至當我教他們「指責」的姿勢時，很多人的手指頭都伸不出來，不敢指向別人，就算要學員向別人說個「不」字都很難。
