On the other hand,since the goods are only presented by the pictures and descriptions,it is hard to tell its reality,so you might have bought something you don’t like,or even the fake one.Of course you can ask for the after service,but it will increase your cost of the time.And the advertisements on the online shops may make you spend much more money on online shopping without being conscious④.

Keep us safe in chat rooms
Today I thought I’d blog about a question that has been asked many times—how do you stay safe in chat rooms?Now I’ll share my experiences with you.
First,there are all kinds of people in chat rooms,you can’t easily tell their identity. So don’t give out too much personal information. Second,protect your privacy. Don’t give out your adress or phone number. Someone may use it to steal your identity. Third,never meet someone you met online alone. Maybe you can meet a bad person,who will do harm to you by illegal actions. Your life may be at risk.
Have you had bad experiences in chat rooms?Do you have some good advice?Post your comment below!
Last month,I met a bad man in the chat room.He said some bad words to me.I was hurt.
One of my classmates met a young man after they chatted in a chat room. The man caught the girl and asked for much money. Luckily,the girl was saved by the police.
