It feels like many of my relatives are really bad people.

This is the older sister who has been cleaning for me all along.
Her son and a classmate (this classmate stayed at her house every weekend during college for four years) started a business and tricked her into borrowing 300,000 yuan.
They promised to pay it back together if anything went wrong. She didn't sign anything, trusting that her son wouldn't deceive her.
But when problems arose, her son and the classmate refused to mention it, claiming she signed the loan herself, and even blamed her for not stopping their startup at the time.
Now she finally paid off her debts after working as a cleaner.
Her nephew then told her to transfer 80,000 yuan to Alipay to quickly set up a company for money laundering, promising a 6,000-yuan daily fee with a 40% commission.
Unless her nephew invests the principal, I think she should only consider proceeding if that happens.
Some relatives are truly toxic tumors.
