What does it mean to live in the world for nineteen years?

Living in the world 19 years means that you are 19 years old. To live in this world is to compare life to a trip. Eighteen years, I have traveled around the world for 19 years, mostly 19 birthdays. Life, like a journey, refers to the process that human beings go through from birth to death. In this process, everyone will experience ups and downs, joys and sorrows, and everyone, everything and scenery encountered during the trip may become unforgettable memories. Life cannot predict the end, but the pace of progress can never stop. Only in this way can we live a real life. Its philosophy and profundity make it an eternal theme of literature and film and television works.
