When the People's Republic of China was founded, walls were demolished in most cities to make way for the expansion of city areas or as a result of criticism for blocking modernization, but the walls are preserved in some cities, such as Xian City and Pingyao.
中華人民共和国時代に入って、市域拡張のため、また近代化の妨げになるという批判もあり、ほとんどの都市では城壁は取り壊されたが、西安や平遥のように保存されている都市も多い。
