1. It is illegal to brush a bill online. Any online brushing that requires advance payment is fraud. Be vigilant when encountering online part-time advertisements that "brush the bill", "brush the reputation" and "brush the credit".

2. Don't have the psychology of "coveting small bargains" and "easy to make big money", don't believe in so-called high returns, and don't click on strange links easily.

When you brush the first order, the liar will give you a small refund to let you taste the sweetness. But when the transaction amount of your bill becomes larger, the swindler will refuse the refund for various reasons. If you have been cheated, don't increase investment in order to recover the "principal". Call the police immediately and submit the other party's QQ, WeChat, telephone and chat records to the police.
