Part of such surcharged was sent to the Kwangtung District for sale; hence they are commonly known as 〝Hunan and Kwangtung Surcharges.〞　　The increase of the international ordinary letter postage from 50 cents to one dollar and of the domestic express letter rate from 20￠to 40￠effective from November 1, 1941 greatly reduced the use of 50￠stamps, which were heavily stocked.　　They were consequently surcharged as 40￠denominations in the Eastern Szechwan, Western Szechwan, Yunnan, Hunan and Kwangtung Postal Districts in accordance with a circular telegram from the Directorate General of Posts. On December 1 of the same year when the domestic ordinary postage was revised, such surcharge was immediately discontinued.
