The word comes from dialect. In Sichuan dialect, "zu" is pronounced as "jio".

The reason why this word began to be a buzzword stems from a common topic "health preservation" on the Internet today. With more and more signs of premature senility such as hair loss and insomnia appearing in young people, young people began to pay more attention to the topic of health preservation, and drinking hot water, thermos cups and soaking jio stalks became popular one after another.

As we can see from the above, there is a topic closely related to this word called "keeping in good health". Nowadays, there are not a few online buzzwords derived from this topic, such as beer soaking in wolfberry, middle-aged greasy, health punk ... and so on.

After the word became popular, it was also made into related expression packs by netizens, which was enthusiastically sought after by everyone and widely used and reprinted. After all, health care has a long way to go, starting with you and me!
