First, liars can switch their voices at will.
In this fraud case, the person who can switch voices at will is not a man, but a woman. If men can reach the realm of women, it is really a powerful fraud gang. This incident also gives us a warning not to believe all the stories of strangers at will, especially when we get a phone call from strangers. We should be more careful, and we'd better not talk to them too much, otherwise a scam may occur during the conversation. When the people of this fraud gang gave a live demonstration, they were really surprised how they could reach this level.
Second, don't give swindlers a chance to cheat us.
We should always be vigilant. If we are vigilant enough, even if the swindlers are really smart, as long as we are vigilant ourselves, they have no chance to commit their fraud. Although the liar is a woman, it is not impossible that he will meet a man posing as a woman next time.
So this fraud gang is very smart, not a man, but it is also very powerful. In the face of strangers, everyone should always be vigilant.
