When it comes to thermos cups, what comes to mind is the phrase "soaking medlar in thermos cups". It seems that the thermos cup has been bound to the word health preservation. Nowadays, young people pay more and more attention to health preservation, and they can often see young people around the age of 20 guarding thermos cups. Once in college, everyone in our dormitory did this, stayed up the last night, used the best mask and drank the healthiest wolfberry tea.

In addition to these young people who pay great attention to their health now, the most common thermos around them all day is the teacher. When I was a student, as long as it was time for class, I would see the teacher coming into the classroom with a thermos cup and their "little bees", chatting for a while, opening the thermos cup and drinking a mouthful of water to moisten my throat, and then continuing to lecture.

With the post-90s coming into the society and becoming talents from all walks of life, the group of teachers is also changing quietly. They are no longer just keeping a straight face, and the thermos cup is no longer just wolfberry tea.

Things like Lycium barbarum and boat-fruited Sterculia can only be said to be the most basic tea in a thermos cup, which usually only appears when the teacher's voice and body are tired. Of course, it does not rule out that some people just like to drink.

Many teachers simply put ordinary warm water or boiled water in a thermos cup. After all, what the human body needs most is water supplement, and water is also the best thing to quench thirst. It is normal to feel thirsty and want to drink water after a hard lecture.
