It was my fiftieth birthday the other dayI was so happy that day.

I have been loved and cared for by my parents, brothers and sisters since I was a child, and after marriage, I have been cared for by my husband, and I have a handsome son and a daughter-in-law who is understanding and satisfied. I am content. I'm satisfied!!

The wheel of fifty, half a century of life. Whether you care about it or not, the years have taken their own steps lightly and tirelessly, shuttling through the tunnel of time and space. Life is an instant, from croaking to the ground, through childhood, adolescence, youth, middle age, and then to twilight.

For me, in the long river of life, I have unconsciously entered the winter of life (November is winter).

Fifty years old, let me feel a lot of emotion, fifty-year-old women, no longer have the initial youth of the rivers and lakes that everyone says, no longer have the brightness of youth, no longer have the unbridled and elegant chic, no longer have a beautiful and beautiful face, but instead of a gentle, gentle, quiet, wise and timeless mature charm.

At the age of fifty, he has experienced countless experiences, gone through a long time, and experienced the tempering of ups and downs. I have gone through the student days of the bookish business and the glamorous years like water, the flying thoughts and feelings, the ups and downs of the difficult days, I want to cry but can't cry when I am in trouble, and I have no room to vent. The 50th birthday a few days ago was also the most brilliant part of the music of my life.

My handsome son's greetings were a perfect end to my birthday celebration. At the same time, it brought me an unexpected surprise, a "tiger cub" son to an empathetic beautiful and gentle daughter-in-law "rabbit baby" proposed a good day, the romance of the son This is the happiest and happiest day I have ever had, the usual busy rush and entrepreneurial time and proud spring breeze, the difficulties of the world and the changes of human feelings, let me understand indifferent in order to be ambitious, quiet to go far.

I'm fifty years old! At the age of fifty, you must cherish more, learn to love yourself and your loved ones, enjoy the true meaning of life, and know how to use your heart and heart to savor and taste the harshness of the winter of life and the omen of snow, which will bring happiness. (Abundance and tranquility).

Fifty years old, fifty years old and farewell to youth ......

Say goodbye to youth and touch the sunset.
