It's just my personal opinion:
Currently, the number of single people in China has reached 200 million. Why do more and more people choose to be single? I think it's caused by a variety of reasons. If we have never met the right person in our relationship, we must be tight-lipped about the relationship. That is, we need to keep our cool heads. If we don't feel love and warmth in a relationship, then we are bound to stumble.
We naturally want to gain more power to sustain a relationship, If we don't always feel love and warmth, or if we're in this relationship and we're not in our position, then our relationship loses meaning and value.
The very important reason is that young people nowadays pay more and more attention to freedom. They love freedom more than anything else.
