Dear Sir / Madam,
   I'm writing to advocate netizens to be responsible for their remarks on the Intemet, especially microblogs. It's noticed that some people publicize eye-catching opinions and even gossip about others to attract attention. I'm really worried about it. It's understandable to compete for attention on the Internet because everyone likes the feeling of being the center of the world. However, the potential risks should not be ignored. The most serious one is that those who create rumors may commit a crime while the major characters in rumors will suffer emotionally. To prevent the risk from becoming a reality one day, netizens should be called on to examine their words carefully.
