This frog-like green colour is rather strange for this old British turbo lady. The plate may be related to the " Rugby Sevens " event in Hong Kong. Please see also my YouTube channel: https://www.youtube.com/user/settime2588
The number "8" is considered very lucky in Chinese numerology. Licence plates with this number are auctioned for sale by the Hong Kong government and they trade at huge prices. This "888" licence plate probably costs more than the car. Please see also my YouTube channel: https://www.youtube.com/user/settime2588
