Xu, a suspected telecom fraudster from Taiwan who police will only refer to by his surname, was repatriated to the Chinese mainland from Kenya in April.
My boss - "Rich Fat Man", as everyone calls him - contacted me in July 2014.He offered me a leading role in his gang after learning that I had been in prison in Taiwan for fraud.
He paid me NT$100,000($3,100) upfront and flew me to Kenya where I pretended to be "the top police officer of the criminal investigation division for financial cases", a role that is always played by someone from Taiwan.
In addition to the basic wage, I got a bonus of 8 percent of the profits each month. In my three months in Kenya I earned 200,000 yuan. We usually ripped off one or two people every day.
An operator used computer software to automatically make phone calls and then played a recording when the phone was answered.
We were divided into three groups. The lowest group read scripts to people who pressed "9" for more information. They told them the police were investigating because their bank accounts had been involved in money laundering. After the first group hung up, someone from the second group would call the victim and urge them to do all they could to assist the police with the investigation.
If we struck lucrative prey, someone from the top group would call the victim and trick them into transferring money to our bank accounts.
I got back into fraud in 2014, four years after leaving jail. It's easy money and the sentences are light if you get caught. Gang members know that even the master minds will not be given heavy sentences. That's why so many people in Taiwan are getting involved in this stuff.
Xu spoke with Zhang Yi.
