HK Tramway - we call the Hong Kong tramway “Ding Ding”." It is one of the oldest means of public transport in the metropolis and was put into service in 1904 during the British colonial period. While the music industry is on the rise in Hong Kong, people support their idols in different ways. One of the “WOW” cases is a promotional campaign by fans on Ding Ding, wishing a singer a happy birthday. The singer was replaced by the cat in the drawing.
