1. Drinks are the standard for New Year dinner in China. Do you know why most bottled drinks are not full?

A: For security reasons.

Analysis: The pressure of an object will change with the change of temperature. If the temperature rises, the volume of the beverage will expand and the pressure will increase. If the beverage bottle is full, once it encounters high temperature, the pressure in the bottle will increase, which may cause the bottle cap to rupture or the bottle body to burst, causing losses or unnecessary injuries. In order to avoid this situation, beverage bottles are generally not full.

For the sake of food safety, the New Year's Eve dinner may be divided into meals. Was there a separate meal system in ancient China?

Answer: Yes.

Analysis: The history of catering system can be traced back to prehistoric times, with a development process of at least 3,000 years. During the Zhou, Qin, Han and Jin Dynasties, the banquet in China was divided into meals. In the late Tang Dynasty and the Five Dynasties, although everyone sat together, food was still given to everyone. After the Song Dynasty, modern eating (drinking at the same table) appeared.
