A "Sir Rowland Hill and the Penny Black" postage prepaid postcard, sent from Wanzai Post Office, Zhuhai to Hong Kong. I very much like the red local postage due of RMB 0.4 chop from China
Date Sent: 1 July 2017 On the cover, I just affixed a Japan 50 Yen out of the normal postage of 90 Yen. You can see the round-shaped T 40/90 chop from Japan. The postage due is thus: ((40 / 90) x 2.3) + 4 = HK$5.
Date Sent: 17 May 2017 On the cover, I just affixed a Macau 2 Patacas Year of Rooster ATM out of the normal postage of 3 Patacas. You can see the round-shaped T 1/3 chop from Macau. The postage due is thus: ((1 / 3) x 2.3) + 4 = HK$4.8.
