When you want others know that you are full, you can place your knife and fork together, with the prongs (tines) of the fork facing upwards on your plate.
当你想让别人知道你吃饱的时候。有可以把你的刀子和叉子和在一起并且把叉子的尖齿朝上放。(如图)。

The fork is held tines down so food is scooped on to the back of the fork. This is a skill that takes time to master.
用餐时叉齿朝下，用叉背盛放食物。这可是个需要长期练习的技巧。

The difference is that you keep the fork in your left hand to take the food to your mouth but with the tines down.
