People know well about reading online. But do you hear “reading on the line?” Line 2 of Shanghai's subway opened a “guerilla library”(流动图书馆). This underground library allows every passengers to borrow a book at one station, and leave it at another station when they get off.
With the help of Aizhi bookstores and Hujiang. com, Metro Line 2 opened the library for the public, and some online education companies also give their help. It helps more people to read books and make better use of their time while they are in the subway. People gave back the books in the next station after reading, and many of them even put one yuan in the “idea box”, which is used for charity（慈善）.
Unlike a traditional library, the Line 2 guerilla library is usually simple and easy. On the corner of every station stand a few shelves of books. Passengers can take their favorite books without any formalities(手续).
Study shows that people today don't need read many books these days. Last year, people in China aged 18-70 read fewer than five books. Most people use the excuse that they're just too busy or reading is boring. Well, some books may be boring, but reading certainly isn't.
