"CHINA" overprints were used exclusively in the leased territory of Weihaiwei until its closure in 1930. During the Second World War, the De La Rue factory in London was bombed, leading to the issuing of a series of George VI definitives printed on thinly-coated paper by Bradbury Wilkinson and Harrison, called the "rough paper wartime printings". Japanese Occupation, 1941-1945 Hong Kong surrendered to Japan on 25 December 1941, marking the start of the Japanese occupation of Hong Kong. Postal services resumed in early 1942, with 20 or 21 Japanese definitives were introduced for use in Hong Kong. As a response to hyperinflation during the occupation, three stamp issues were surcharged with a higher value. These were also overprinted with "Office of the Governor of Hong Kong" (). Censorship, changes of local addresses into a Japanese format, and renaming of district and building names into names of Japanese origins led to a chaotic postal system during the occupation. Most of the British stamps were safely hidden until Japan's surrender. Some were stored in the vaults of the General Post Office and the Hongkong and Shanghai Banking Corporation building, while others were sent to Australia and South Africa for safekeeping. Post-War, 1945-1997 Japan surrendered on 15 August 1945, and postal service under the British resumed on 25 August, initially for free. No stamps were available, so octagonal handstamps inscribed with ‘HONG KONG 1945 POSTAGE PAID’ were later used in lieu of stamps. In early September, the government rediscovered the stash of hidden stamps. Together with the return of the stamp cache from Australia and South Africa, the sales of stamps re-continued on 28 September. The end of the Second World War saw the release of the "Victory" commemorative stamps (30 August 1946) on the anniversary of the British takeover. The 30-cent and 1-dollar stamps were designed by Postmaster Edward Irvine Wynne-Jones and Chief Draughtsman of the Public Works Department William E Jones during their internment in the Stanley Internment Camp by the Japanese. The design featured a phoenix with the Latin text "1941 RESURGO 1945", along with the Chinese text "鳳鳥復興 漢英昇平" (Phoenix Resurgence; Han-British Peace). The Chinese text was rendered as "鳳鳥復興 漢英大和" in the original draft, which had the same meaning. However, as "大和" was also a rendition of "Yamato", the text was changed to alternate Chinese characters. The same month also saw the return of some George VI definitives
