With the advancement of science and technology, cellphones have acquired many functions in our lives, gradually taking the place of cameras, sound recorders, or even some tasks of the computer.

Li Gang, a member of the China Photographers Association, took his lens on the interesting subject of people using cellphones.

To him, the invention of the cellphone was to serve people and make life easier, but nowadays more and more people are "abducted" by their phones.

People now cannot get away from their phones, with their eyes glued to the screens all the time.

Li's photographic series Cellphone's World shows that cellphones are encroaching on people's lives and making them detach from their surroundings.
