Once a month, I go out with a group of Chinese friends who come from different countries. We are Chinese people from the PRC, Taiwan, Malaysia and Singapore of course.
One of their habits that annoys me the most is that they place/poke their chopsticks vertically into their food or rice bowl. For me, it is a No-No. Let me tell you why! My mum and most elderly folks would say if you do that, it means the rice is an offering to the ghosts. The chopsticks are positioned like joss sticks used for a funeral. If you eat the rice, it will bring you bad luck. Besides Singapore, places like China, Japan and Korea also believe this. Therefore, it is best to avoid placing chopsticks vertically into the food or rice. Now let me tell you more about other Chinese table manners you should observe.
