In Hong Kong, I think that the most popular home entertainment is watching TV. As you know, Hong Kong people are very hectic because of their study or work. Therefore, they do not have much time to relax themselves. After schoolwork or work, Hong Kong people already have no energy to play. As a result, they will stay home and sit on the sofa watching TV. There are a variety of TV programs for them to select. Gradually, they will be addicted to television. Moreover, they will want to catch the episodes.
However, watching too much TV will lead to some potential side effects. For students, if they watch too much TV, they may get short-sight or eye strain. Additionally, they will neglect their homework due to watching the TV programmer. For adult, they may not exercise owing to the fact that they spend all the time on watching TV. Also, they may be fat since they sit on the sofa for a long time without movement. Watching too much TV also will affect their communication with their families. If a family lacks of communication, their relationship will be ruined.
In a nutshell, watching TV is a good entertainment when we feel dull at home. Besides, watching TV also can help us to relax our anxious emotion. But if we watch too much TV, it may be harmful to us. Thus, we need to control ourselves in order not to be obsessed with the TV.
