Suddenly, 2008 was already ten years ago. Our youth is drifting away unconsciously. What a wonderful thing it would be if there was a diary that could completely record the youthful growth process of those born in the 1990s, and allow us to stop and look back on the warmth and touch that once belonged to us. Where and Anfang have such a youth diary, from 2008 to 2018, without interruption for ten years. Open their diaries and let us relive our own youth together.
