Newest mail: 19 May, 2011
The most recent letter I got from Hong Kong is the one posted on 19th May, 2011. The cancellation is clearly legible and the stamp shows "Des Voeux Road West" in Hong Kong.
Yet, personally I prefer the letter above, which was sent not a lot earlier than the one on top. According to the cancellation the date of posting is 27th April, 2011. The stamps are much more interesting here featuring the birds of Hong Kong as well as the Centenary of Railway Service in the country.
