Provinces of China
The Republic of China, established in 1912, set up four more provinces in Inner Mongolia and two provinces in historic Tibet, bringing the total to 28. In 1931, Ma Zhongying established Hexi in the northern parts of Gansu but the ROC never acknowledged the province. However, China lost four provinces with the establishment of the Japanese puppet state of Manchukuo in Manchuria. After the defeat of Japan in World War II in 1945, China re-incorporated Manchuria as 10 provinces, and assumed control of Taiwan as a province. As a result, the Republic of China in 1946 had 35 provinces. Although the Republic of China now only controls one province (Taiwan), and some islands of a second province (Fujian), it continues to formally claim all 35 provinces (including those that no longer form part of the area of the People's Republic of China).
Galeote Pereira
Pereira's manuscript starts in the style of a geographical overview. Like most later geographical works on China, he starts with listing China's provinces ("shires", in Willis' translation), stating that there are 13 of them, giving names of 11 of them and a brief information about some, and concluding that for "Confu", Yunnan and Sichuan, "how many towns [those] three shires have, we are ignorant as yet, as also of the proper names of the twelfth and thirteenth shires, and the towns therein". This shows that Pereira (or his early Jesuit editors) were not in possession of the information that the Lisbon historian João de Barros had when writing the Third of his "Décadas da Ásia" (published 1563, but written much earlier), which correctly lists all fifteen provinces of the Ming China.
