The key hanging on the belt is healthy.

In fact, if you look closely, some people still do this now, but more are elderly people. It was really popular to hang the key around your waist in the early years.

First, convenience.

You don't have to rummage around for keys, especially some men don't like to take their bags when they go out, but there is no place to put them, so it's convenient to hang them around their waists.

Men forget things easily. Hang the key around your waist so that you won't forget when you go out.

Second, the symbol of status.

In ancient times, there was a saying called "Fu". Hanging good things and valuable things around your waist is also a symbol of status.

Just like hanging the car keys on your waist, people can see at a glance that it is the owner, more or less ostentatious.

But now everyone doesn't do it. First of all, owning a car and a house is no longer something to boast about. Nowadays, many people have bought their own houses with loans, and cars have become a means of transportation, which many families have.

Besides, there are fewer keys now. At present, there are only 1~2 keys in the front door of the house, and smart locks are gradually adopted in many places, reducing the number of keys. It turns out that everyone will carry the keys to cabinets and drawers with them, for fear of losing them.

But some families even use smart locks at the door, so there are not as many keys as before. The safe has also been changed into a password lock or a fingerprint lock.

What is more important than the key now should be the mobile phone, so as long as you keep it safe, you will be safe when you go out. So now no one can see the key hanging around his waist, but some men can hang their mobile phones around their waist.
