Jiojio's meaning
It sounds a bit like little jiojio. Many netizens think that little jiojio sounds cuter, so they will use the word little jiojio instead when talking about little feet. Nowadays, many netizens will also use the word little jiojio when describing the paws of cats or puppies.
Originated from a common topic on the Internet, "keeping in good health", with more and more signs of premature aging such as hair loss and insomnia appearing in young people, young people began to pay more attention to this topic, and drinking more hot water, thermos cups and soaking jio stalks became popular one after another.
