In 1914, the city changed back to its old name Shenyang,[27] but continued to be known as Mukden (sometimes spelled Moukden) in some English sources and in Japan through much of the first half of 20th century. The postmark of the Chinese postal administration kept the spelling "MOUKDEN/奉天" for usage on international mails until the late 1920s. After that, a Chinese–Manchurian bilingual type "SHENYANG (MUKDEN)/瀋陽 (奉天)" datestamp was used until 1933.
