More and more Chinese can’ t live without their phones. Many of them, including the elderly, use smart phone apps to keep in touch and enlarge their circle of friends. They also use phones for shopping and searching information because phones are easy to carry. Besides, it is cheaper to communicate by mobile apps than by traditional phones. However, this new trend also leads to people’ s over-dependence on mobile phones when socializing. In fact, some young people have become so addicted that they ignore the face-to-face communication with their families and friends.
