First, protect your nails. Ancient concubines also liked to keep their nails, and some people especially liked to keep long nails. If they show their nails, they will easily wear out, so wearing a nail cover will effectively protect her own nails and only take them off when sleeping or taking a shower. If it is a long nail, it can effectively avoid problems such as nail breakage. We all know that if you accidentally break your nails, it is very painful. Their fingernails are equivalent to putting a protective cover on your nails.
Second, beautify the nails and modify the hand shape. Similar to our modern girls' nails, ancient concubines had nothing to do. Because they loved beauty very much, it was very particular to study how to become beautiful. From head to toe, of course, nails will not fall off, and nail covers are equivalent to nails, which are flexible to use and can be said to be very wise. Moreover, the nail sleeve is generally long, so wearing this nail sleeve will also make your hands look slender, thus beautifying your hands.
Third, symbolic status. In ancient times, there were handmaids and concubines. Generally speaking, maids must do some clumsy work, such as cooking, chopping wood and carrying water. So the loss of nails is great. Generally speaking, they can't keep their nails and wear these things, which affects their work. So most of them are concubines, and people of different grades wear different colors and materials, so this finger cover is very particular and can symbolize status in a sense.
