In China, the vacuum flask is regarded as the standard equipment for leaders. In fact, not only leaders like to use thermos cups, from high school students to middle-aged and elderly people, regardless of men, women, old or young, like to use thermos cups. This has developed into a social culture in China. What is the magic of the vacuum flask that can make the Chinese people, especially the leaders, fall in love with it. My analysis may have the following reasons: First: physical needs. First, provide heat to the body. Most people who can achieve leadership positions are still a bit old, mainly middle-aged and elderly people. At this age, the body’s metabolism slows down, and the body’s calorie needs cannot be met by the body’s own metabolism. Therefore, they can only find heat sources from outside the body. And boiled water is the way many Chinese people replenish heat every day. So, in order to be able to drink boiled water at any time, a vacuum flask has naturally become a must-have for everyone. Secondly, provide moisture to the body. As a leader, it must be that the conference is constant every day, small meetings are commonplace, and the time to deliver speeches is very long, and the result is dry mouth. At this time, you need a cup of hot water to moisturize your throat. If it weren’t for holding a thermos cup in his hand, wouldn’t he have smoke in his voice? Second: work needs. Some people may wonder why a thermos cup is needed for the work of a leader. The thermos cup should be a very ordinary and civilian object. The reason is here. Leaders need us to do our work well, and they don’t want to have a strong sense of distance with ordinary employees. Therefore, we will also look for some ways to get closer to ordinary employees, and the vacuum flask is a good choice. Employees need to drink hot water, and leaders also need to drink hot water. When they met in the hot water room, they said hello to each other and talked a few words, and the relationship between everyone became more friendly and harmonious. The work can also be better carried out. Third: health needs. When people reach middle age, various physical discomforts begin to appear. Nurturing is an important part of work and life. Soaking wolfberries in a thermos gradually becomes more commonplace. On the one hand, using a thermos cup can be more convenient and sanitary. In fact, cups, tea, etc. will be prepared at the venue. However, these things are used as public goods. I don’t know how many people have used them. I don’t know if the waiter can clean the cups. Therefore, it is more hygienic and safe to bring your own cups. On the other hand, the thermos cup is convenient for drinking medicine, tea, and health tonics. When people reach middle age, it is inevitable that some people will have some chronic diseases and need to take medicine regularly. It is much more convenient to have a thermos cup in hand. Of course, more often than not drinking tea and health products. Whether it’s brewing black tea, green tea or American ginseng with wolfberry, the vacuum flask is easy to use and convenient. Nowadays, the vacuum flask is not only the standard equipment for leaders, but more young people have also joined the vacuum flask team. At the end of last year, Liu Haoran’s photo of holding a thermos mug went viral on the Internet for a while. Some netizens ridiculed “Is the wolfberry soaked in the thermos, Master Beijing”, “The health preservation is very good”, and some netizens made funny comments saying “Let I will become a thermos.” As a post-95 Liu Haoran, holding a thermos cup in hand, showing off the image of an old cadre, people can’t help but laugh. But it also shows that more and more young people like to use thermos cups. I am also one of them. In fact, I have been using a thermos for a long time, starting from high school and continuing to university, and it is even more inseparable for me to participate in work now. When I was in high school, I used a large plastic cup of 800 ml. After every morning study, I had to dry half of the cup to relieve the fatigue of my throat. After arriving at university, I slowly began to pursue the quality of the cup. Replace the plastic water cup with a stainless steel thermos cup. Now that I have joined work, I have income, and my budget is more sufficient. Not only is it required that the thermos cup can have a good insulation effect, but also have a high value, which is not only easy to use, but also beautiful. No way, this eldest lady is Yan Kong. At Christmas last year, the male ticket said that he would give me a thermos mug, and said it was a limited edition for Christmas. I definitely like it. I’m quite looking forward to it. Later, on Christmas Day, I saw him downcast, and I didn’t know what was wrong. After asking, I realized that this silly boy didn’t grab the Christmas limited edition water glass. This is the one below. Then, he bought a non-limited edition LOCK&LOCK vitality mug, which is the following. To be honest, I actually prefer this non-limited edition. I am more enthusiastic about minimalism, and I also demand the same for my daily necessities. So, as soon as I saw this pale green thermos mug, I liked it. In particular, its one-key open lid design has greatly appreciated. Every time one hand is playing on a mobile phone, the other hand can also easily open the bottle cap to replenish water in time. But I am still a person with clear grievances. For the male ticket to choose a cup for me, I was satisfied in the end, and I rewarded him with a kiss. But I didn’t understand my preferences for him for so long, and I punished him to make my humanoid cup holder. As long as I go wherever I go, he will be responsible for helping me to follow with the Lock and Lock vitality cup, huh. Later, I also sent him a black lock and lock vitality cup of the same style. Two people holding a thermos together can be more energetic!
