As you know, the Chinese are distinguished by their hospitality, and it is customary for them to arrange dinner with all family members at the same time, opening a large table and preparing various delicious dishes. A typical Chinese table is round, with smaller round glass that rotates.
All dishes are placed on glass, which all rotates and allows all family members to try the dishes in turn. Round glass rotates either automatically or with the help of one of the family members.
One of the interesting aspects of using the round table is that if you do not have time to use the dish in front of you, you will have to wait until the circle turns around again and it appears again in front of you.
You can take a dish from a common plate in a circle with a stick and immediately eat it without putting it on your personal plate.
