Located on the banks of the Tamsui River, between the MRT station and the ferry terminal, 686 was quietly opened in late 2006. One of the owners is a poet, and the other is a film critic, which is why the store pays special attention to poetry collections and film categories. The poetry collections have a special section that showcases the owner's private collection of out-of-print books, which are only displayed and not for sale. The store primarily stocks new books, categorized into literature, film, ecology, travel, and more. A coffee bar is attached, hosting irregular events such as movie screenings and discussions, new book launches, poetry readings, independent musician performances, and discussions on various social issues. This aims to preserve a bit of literary and poetic voice amidst the increasingly commercialized bustle of the riverside.
