What does the fortune teller mean when he says I have one and a half brothers?

Smart, broad-minded, ambitious, young people are diligent and famous, young people are unprofitable, have many plans in their stomachs, have manners, are talented, work hard and have no money in their lives. Dealing with people is not beautiful, its six relatives are reliable, making friends and enjoying the spring breeze all over the world. In the middle limit, you can shine brilliantly, see good and not bully, not be afraid of evil, follow good advice in everything, live within your means, be a lucky person, become famous all over the world, and finally get married and settle down in your later years, with many tall buildings.
