You should never perch your chopsticks between the thumb, middle, ring and little fingers, while sticking out your index finger, as it implies abuse. In most cases, Chinese people point at others with their index fingers to scold them. Therefore, such a movement is unacceptable. It is also considered bad manners to point at others,with your chopsticks, while chatting during a meal.
这种做法也是极为不能被人接受的，这种拿筷子的方法是，用大拇指和中指、无名指、小指捏住筷子，而食指伸出。这在北京人眼里叫“骂大街”。因为在吃饭时食指伸出，总在不停的指别人，北京人一般伸出食指去指对方时，大都带有指责的意思。所以说，吃饭用筷子时用手指人，无异于指责别人，这同骂人是一样的，是不能够允许的。还有一种情况也是这种意思，那就是吃饭时同别人交谈并用筷子指人。
