Youth is like a rushing river, flowing onward and never to return.
In childhood, innocent smiles graced our faces. We held pinwheels and ran across green lawns, our parents trailing behind us, sweat beading on our foreheads without us even noticing. There were no worries then, no sorrows.
In adolescence, we walked home with friends, backpacks on our shoulders, humming the latest rock songs. When we had sorrows, friends shared the burden; when we had joy, friends shared the delight. Gradually, we matured and grew up.
In adulthood, we stepped out of university full of dreams, hoping to carve out a bright future. Bit by bit, we acquired cars and homes. We transformed from eager novices into seasoned professionals, and our homes evolved from couples' worlds into families of three. Happiness overflowed, and tranquility emerged.
Now, silver threads appear at our temples, and our bodies are not as robust as before. Having stepped back from the workplace, our children have grown up, bearing a resemblance to our younger selves. There is no regret in our hearts. The setting sun approaches, and the day ends with composure.
Farewell, youth. Looking back on the past, I am filled with deep emotion. Time passes like a white colt through a crevice; in a flash, more than half of life has gone by. Only youth is what I cherish in memory.
Farewell, youth.
青春恰似奔流的江河，一去不返。
儿时，天真烂漫的笑容挂在脸上，手拿着风车，在翠绿的草坪上奔跑着，身后是跟随的父母，不经意间额头上已渗出细汗。那时没有顾虑，也没有伤愁。
少年时期，背着书包和几个同学一起走在回家的路上，嘴里不时哼唱着最新的摇滚歌曲。有了忧愁，有朋友分担；有了欢乐，与朋友分享。我们在分享中渐渐成熟，渐渐长大。
成年后，满怀梦想地走出大学校园，渴望闯出一片美好的蓝天。一点点拥有了车，一点点拥有了房，从初出茅庐的新人变成了职场高手，家里也从二人世界变成了三人家庭。幸福洋溢，恬静流露。
如今，鬓角已显几根银丝，身体也不像以前那样强健。从职场上退下来，孩子也已长大，眉眼间竟有几分我年轻时的模样。心中再无遗憾。夕阳临近，落日从容。
再见，青春。回忆起曾经，感慨万千。时间如白驹过隙，恍惚间已过大半生，唯余青春值得怀念。
再见，青春。
