On a lazy Friday afternoon, a small group of primary school students open their laptops and, laughing and chatting, plunge straight into the world of computer programming.
The children, starting as young as six years old, come each week to this out-of-school private learning centre in Hong Kong.
They are getting lessons in computer coding not always available within Hong Kong's state schools, with parents paying extra for skills that they hope will keep up with a fast-moving digital industry.
Over the next hour-and-a-half, they are taught how to create characters for a simple mobile game, using "drag and drop" software.
