What do you mean, "Forty-nine years is the end of luck, osmanthus fragrance is used instead of flowers, and husband and wife will grow old together for a hundred years"?

It is said that it is the prediction method of Yuan Tiangang in Tang Dynasty, and it is the life of young people struggling to get rich in their later years. Substituting flowers means that people who are nearly 50 years old are like rotten wood, but if young and beautiful girls become partners at this time, the fate of the Lord will be as youthful and energetic as osmanthus in the Mid-Autumn Festival, and they will reap great wealth. So work hard, be a late bloomer.
