Why is cancer central air conditioning?

Cancer men will become central air conditioners, on the one hand, because they hope that this will increase others' goodwill towards themselves, make this girl like herself, and then have the right to choose.

On the other hand, Cancer men are still male chauvinist in their bones, and like to take care of people who are weaker than themselves, especially girls. They will be enthusiastic when they see the place where they need help. In fact, many men become central air conditioners. Apart from natural skills or acquired tutoring, they also lack love. Only when they are kind to others can they get recognition and get corresponding love responses.
