Soaking Lycium barbarum in a thermos cup usually means keeping in good health in middle age. The complete statement of the stalk is "people have to soak medlar in a thermos cup when they reach middle age." In addition to "thermos cup and medlar", there is also "beer and medlar", a middle-aged Buddhist with a contemporary mentality who commits suicide while maintaining health. "Wear eye cream when staying up late", "Eat Jianweixiaoshi tablets when overeating" and so on.

The stem originated from 20 17. A blog post in Weibo lamenting the time and poking fun at Black Panther band drummer Zhao Mingyi wrote: A middle-aged balding photographer friend played rock and roll when he was young. Some time ago, he went to take photos of Black Panther band, and when he came back, he was deeply moved. It's unimaginable! It's unimaginable! In those days, the average man in Iron Man came to me with a thermos cup! Zhao Mingyi himself sent Weibo a response: I heard that my thermos cup caught fire in the Weibo? Netizens have teased, maybe it's Lycium barbarum in a thermos cup, it's middle-aged health care, which makes stalks popular on the Internet.
