Beginning November 1, 1922 postal rates were revised-postage for postcards and printed matter was raised from 1￠ to 2￠ and for letters from 3￠ to 4￠ . The approach of Christmas and New Year’s Day and the consequent increase of greeting cards caused a great demand for 2￠ stamps. Further the raising of postage on ordinary letter mail to 4￠ had reduced considerably the use of 3￠ stamps, of which there was a large stock left. Arrangement, therefore, was made with the Printing Bureau of the Ministry of Finance, Peking for surcharging a part of the 3￠ stamps to be 2￠ by a plate which overprinted 50 stamps a time. In the middle of the stamp is the overprint of the big Arabic figure 〝2,〞under which is the word 〝Cts.〞 and on both sides of which are No.5 Sung characters 〝暫作貳分〞 (temporarily surcharged as 2￠ ). The original face value in four corners was covered up with small stars. In 1930 when 1￠ stamps were required to match the stamps of other denominations for mail franking purpose, another lot of 3￠ stamps was surcharged as 1￠ , also by the Printing Bureau of the Ministry of Finance, Peking. At the top of the stamp is the overprint of Arabic figure 〝1〞 and at the bottom is the word 〝Ct.〞 in English, while the Chinese wording in No.5 Sung characters 〝暫作壹分〞(temporarily surcharged as 1￠ ) appears on the sides. The sale commenced at the end of October.
