Song Chunfang’s former residence is located at No. 6 Fushan Branch Road, also known as Heimu Lu. In the history of modern Chinese book collection, Song Chunfang is considered a world-renowned collector. He primarily collected drama books and periodicals, earning the reputation of being one of the ‘three great drama collectors in the world.’ Heimu Lu mainly houses foreign original drama books and periodicals, with many rare editions that are hard to find abroad. There are instances of foreign scholars writing letters to borrow books from their own country. This private book collection building has not only become a cultural magnet for Qingdao but also a global landmark for theatrical culture. Open all year round, accessible 24/7, and the exterior is open all day long.
