1. For the sake of food safety, you may wish to share meals during New Year gatherings. Was there a "separated meal system" in ancient my country?
Correct answer:some
In ancient China, the history of sharing meals can be traced back to prehistoric times, with a development process of at least three thousand years.
During the Zhou, Qin, Han, and Jin dynasties, our country’s banquets were divided into separate meals. During the late Tang Dynasty and the Five Dynasties, people sat together, but the food was still one for each person. After the Song Dynasty, the modern meaning of banquets (sharing meals at the same table) ) just appeared.
When ancient Chinese people shared meals, they usually sat on the floor with a small, low table in front of them. Light tableware was placed on the table, and heavy and large utensils were placed directly on the ground outside the mat. "During the Shang Dynasty, humans invented the rammed earth technology. Because the rammed earth technology could flatten the ground, the earliest indoor furniture in Chinese history began to appear, and that was the 'mat'." Yu, the intangible inheritor of the furniture waxing technique Hongyan pointed out, "In those days, we sat on the floor. Eating on the floor was called a banquet. The most honorable position was called the chairman. After eating, it was called leaving the banquet. At that time, everyone knelt on the table and ate their own food. This was the meal-sharing system." The banquet and mat in the "banquet" are actually mats, which is a reflection of this ancient meal-sharing system.
2. When you return home from an outing, which disinfectant is more suitable to disinfect the surface of your mobile phone?
Options:
75% pure alcohol
Diluted 84 disinfectant
Correct answer:75% pure alcohol
84 Disinfectant is a funny disinfectant based on sodium hypochlorite. It is corrosive to metals. Generally, disinfecting items need to be soaked for 10-15 minutes to be effective. It is not suitable for mobile phone disinfection. Alcohol with a purity of 75% is non-corrosive and volatile, and will not cause irreversible damage to the human body or mobile phones. It is more suitable for surface disinfection of mobile phones.
75% alcohol and 84 disinfectant, both of which can play a very good role in disinfection and sterilization. Each has its own scope of application. It is impossible to say which one is better one-sidedly. Both are better, mainly based on their own characteristics. Choose according to your needs.
Alcohol can cause some fires, so you must pay attention to safety when using it, avoid fire sources, and pay attention to surrounding safety when spraying alcohol.
When using 84 disinfectant for disinfection, you also need to pay attention to regularly opening windows for ventilation, mainly because 84 disinfectant will cause certain damage to the skin and mucous membranes, so try to keep it out of the reach of children.
If alcohol and 84 disinfectant accidentally enter the eye mucosa, you need to rinse it with plenty of water. If necessary, you need to go to the ophthalmology department for further examination and treatment.
