There is no doubt that people all around the world use social media apps most every day. People in different countries have their own favourite apps for communicating. When we open these kinds of apps, we have a lot of online friends., and we have joined into a variety of groups for talking about different topics which usally refer to work, life, education,food etc...... In China, the social media app we use most called Wechat. It is a tool that not only for chatting,but also for payment, watching video or doing business. We can do everything via it. Our lives have been changed a lot since it was created 12 years ago. It was developed to make everyone's life to be convenient. In fact, we are not happy to spend our life only with a phone. Our life should be full of a plenty of interesting things. Cooking food is more excited than ordering takeouts. Having a walk in a park is heathier than watching videos all day long. So, a thing which is popular doesn't represent that it's right!
