白丁友记-书信慢社交，做彼此的树洞

If some things are hard to say in real life, with no one to confide in and unwilling to discuss publicly, try our Tree Hole. Send your messages here, and you’ll surely receive a response.
Of course, you can also use text, images, or voice recordings to document your life here. Whether you’re looking to make pen pals, audio friends, secret friends, or book buddies, or become a voice narrator for our radio station, there’s always a place for you.
For online pen pals, we simulate real-life correspondence. Based on different usage needs, we’ve set varying delivery times for stamps, and offer stamp designs, letter paper, and envelopes in various styles, with monthly updates. If you enjoy collecting, this is a great place to start.
Secret Friends are those who exchange diaries with each other, feeling like their lives are right before your eyes, within reach. Every day at midnight Beijing time, both diaries update, and until you open them, there’s an endless anticipation—because you never know what kind of life the other person wrote about that day. It’s as addictive as binge-watching a series, yet always full of unknown plots. The most reliable connection here might just be saying to someone: “Let’s be Secret Friends.”
The Late Night Radio Station opens every night from 8 PM to 5 AM. Though the night grows deep, you’re never alone, because here we share stories of people around us—come listen, come read aloud, or simply let us keep you company.
