Do young people nowadays usually change the tightness of their sleeves, trousers and other clothes themselves?

This thing is very simple. It is estimated that the post-8s generation should be able to master this skill, but the post-9s generation will be afraid to say it. The elders must be more frugal. It won't take a few minutes to change this job. If you go out, you will have to pay 1 yuan now. Of course, if you have money, you can take it out, which is equivalent to buying a little convenience with money and saving yourself a little time, but the money spent is really worthless, because there is basically no technical content, and normal people can do it by themselves, just to see if they are willing to do it.

Actually, just try it yourself. It's easier to put a pin on the elastic band and put it inside.
