察哈爾省
In China, during the Chinese Civil War, many of the areas controlled by the communists were called 'Border Areas', because they were in remote districts on the borders of two or more provinces. They are also known by the names of 'Border Regions' and 'Liberated Areas' in English. Examples include the Shaan-Gan-Ning Border Region and the neighbouring 晋-察-冀 Jin-Cha-Ji (short for Shanxi Province, Chahar Province and Hebei Province) Border Area in North China.
