How old is the property engineering manager?

Everyone contributes something.

Young people are inexperienced and easy to jump ship.

I'm afraid I can't keep up with my physical strength when I'm old. The maintenance of property facilities and equipment is a big part. Limited energy may not cover everything.

It is best not to recruit managers specifically, but to train them from ordinary employees first. Then compete according to personal ability and responsibility.

Usually it's better to be in your forties.

I hope to give you a reference.
