The Map of All Countries, i.e. the map of the whole world, was compiled during the missionary course of Matteo Ricci in China. In the 36th year of Wanli in the Ming Dynasty (1608), it was copied by the palace eunuchs, which was originally 6 screens and later linked as one map. And then it was re-mounted as a banner, thus becoming a whole map of the world 192 cm long and 380.2 cm wide. The original map has lost, and there are only two maps existing in Mainland China: one is the block-printed edition named Liangyi Xuanlan Map collected in Liaoning Provincial Museum and the other is color-painted copy edition of The Map of All Countries, the one collected in the Nanjing Provincial Museum.
