## What is 白丁友记?

如果有些话，在现实生活中是难言的，没有倾诉对象，又不想公开讨论，试试我们的树洞吧，往这里的投递，你一定能收到回应。

当然，你也可以在这里用图文或是声音记录生活，不论是结交笔友、音友、秘友、书友，还是成为电台的声音讲述人，一定有你的栖身之处。

对于线上的笔友，我们模拟现实通信，根据不同使用需要设置了邮票的寄送时长，而且提供不同风格的邮票、信纸和信封，并且每月都有相应更新，如果你有收集的习惯，不妨从这里开始。

秘友，是交换日记的朋友，对方的生活仿佛就在眼前，触手可及。每晚的北京时间零点更新显示彼此日记，在打开之前，你会永远期待，因为不知道ta今天写的会是怎样的生活。就像追剧一样沉迷其中，但永远是未知剧情。在这里最可靠的关系，大概就是对ta说出——交个秘友。

深夜电台，每晚八点开放至凌晨五点，夜色深沉但我们并非孤独无依，因为这里讲述的是身边的你我故事，来听，来念，或者——来让我们陪伴你。

来白丁友记，开创属于你的网络多维空间吧~
