The Civilian Mobile Library offers books for free. Readers are invited to take one book every 15 days. They are encouraged to pass it on to someone else once they've finished reading. And they are not expected to return the book.

The library is just seven square meters in size but houses thousands of books on different subjects. "It might be the smallest library in the world," said Xu Dawei, the owner. "But in another sense, it's also the biggest because the books keep moving. Once, a reader took a book on Chinese garden history. After finishing it, the reader passed t to a neighbour. The neighbour then took it to Germany!"

"I've read thousands of books," Xu said." Books have truly changed my life." The idea of starting a library took shape in 2000, when Xu recommended（推荐）online a list of his favorite books to university students, but many of them said they couldn't find those books in their school libraries or local bookstores. So he began sending his books to readers for free. "They all wrote me letters expressing their thanks. It inspired me to take it farther, turning my book-gifting into a physical space," Xu said.

"All the readers have to do is come. Even if they finish a book and decide not to pass it on, at least the book benefited（使受益）one person and perhaps their family, helping them fall in love with reading," Xu said. "And this is my dream."
