Two years ago I went to Qiandao Lake, and there was a Lock Culture Museum on it. The biggest gimmick in the museum is a chastity lock. It is said that no one has known how to use it for thousands of years.
A crowd of people crowded in front of the display cabinet with the chastity lock, secretly guessing where to put such a thing and how to use it. There were so many people that I didn't see the lock.
But I think a chastity lock may not necessarily be a lock.
Maybe it's just a token. You know there are women in the world who are very infatuated. Once they identify with someone, they will be with them for life.
Locking people with things may be just locking hearts with feelings.
