Christmas card dated Xmas 1932 which Mildred Dibden made from postage stamps and sent to her brother in England. You can just make out the date on one of the stamps. This was her second Christmas in Hong Kong when she was at the BCMS Children's Home in Broadwood Road. That would suggest that the view is near there (Wanchai/Shau Kei Wan?) looking towards Kowloon, and we see a Chinese man fishing. His hairstyle is a carry-over from the Qing Dynasty, when it was obligatory for men to wear their hair in a queue or pigtail, and shave the front of the head. When that ended in 1911, queues were cut off, but it seems the style/fashion remained, as here in 1932.
Regarding the inscription, Mildred had had a year of learning the Chinese language and practising the script when she wrote this (quite beautifully!). It's a verse of scripture from Isaiah 30:15 - 'In quietness and trust shall be your strength.'
