Limited to 500 words Time flies by and we have already passed our thirties. Looking back on the ordinary life of more than 30 years, nothing seems to be particularly memorable or memorable. However, every little thing that can be recalled connects my childhood, my youth, and my vivid life in my memory. It also reflects the 30 years of great changes in this society, the rapid development of the economy and national strength, the great improvement of the society's material living standards, and the many social phenomena that have occurred either filthy or ugly. So, as I look back at the moment when life has come to an end, I think I should write something about it. No matter whether it is wonderful or not, it is the right to commemorate it. I dream that one day I can talk about it when I am faltering. Of course, I also hope that many people of the same age like me can find the shadow of their youth in it.
