Ofo is very popular nowadays, which brings great convenience to people. For foreign media, they even treat Ofo as one of new four inventions in China. I like to use Ofo so much. I can take exercise and enjoy the scenery. But the news reported that a lot of Ofos had been destroyed. some were stolen and some were broken. Ofo is the new industry, which needs to be supported. While some people's bad behavior hurts public's interest. I believe that most people will protect the bikes and they return them on time. It is everybody's duty to protect the public property. Don't be greedy for the small advantage.
