DON'T Dropping Chopstick(s)
It is considered a serous breach of etiquette when one drops his/her chopstick(s) on the ground, as Chinese people believe it disturbs the ancestors, who are buried. However, this can be rectified by making crosses with the fallen chopstick(s) from east to west, and then from north to south. While picking up the chopstick(s), the person should murmur "I am a damn fool," to express his/her regret.
You should always take great care not to break the above-mentioned 12 taboos. By using a pair of chopsticks politely, you may catch a glimpse into China's profound culture.
