A forehead like that means...

a bad relationship with the father 

and bad chances of luck in academic studies.

 

usually leaving school and starting work at an early age.

 

He has unclear chances of luck before the age of 30, 

and it seems that there is... 

no point (to no avail) no matter what he does.

 

 A woman with such a forehead does not usually have a good chance of marriage, 

and she must marry a man who is at least 10 years older or younger than her.
