How to Stay Safe Online
As we know, with the development of technology, the internet is more and more popular. It’s helpful and interesting. But we also know that it’s not always safe.

First of all, we must never show our personal information to strangers online, like our full name, phone number, address or birthday, to avoid our privacy being stolen.
Second, we should say no to those unfamiliar websites and strange emails, and never click on unknown links in case we get tricked by online fraud.
Third, if we make friends online, we can't meet them in private without telling our parents, because it is very dangerous to meet a stranger we don't know well alone.
What's more, we should develop good online habits, and don't spread unconfirmed messages on the Internet.
If we follow these rules, we can enjoy the convenience of the Internet while staying away from online risks.
