The flag consisted of a British blue ensign with an emblem containing a pair of Mandarin ducks.
However, the Commissioners of Weihaiwei in Liu-kung Tao (劉公島) used a Union Jack combined with a badge of a Chinese imperial dragon on a yellow background.
He wrote to them stating: "The design of the flag hitherto used by the Commissioner of this Dependency is a dragon on the Union Jack and is in my opinion quite unsuitable.
I have therefore to request that the Crown Agents may be instructed to have made for the use of the Commissioner two new flags, the device of the Mandarin Duck being substituted for the Dragon, which is as you are aware the national emblem of China and not appropriate in the case of a British Dependency".
The ducks consist of a male in the foreground and a female in the background drinking from a stream while standing on a reed-covered bank.
