We can ask the other party to provide relevant certificates or business licenses to prove that she does run a beauty shop, and we can check whether the shop really exists by searching relevant information. If she can provide relevant evidence and it is consistent with the information we have found, then her identity is more credible.
We need to pay attention to what she mentioned about investing in crude oil. We can ask her more details, such as investment methods, risk control measures, expected returns and so on. If she can give a reasonable and detailed answer and show some knowledge and experience in the crude oil market, then she may be a trustworthy person.
In the dialogue, we can also observe whether her words and deeds are reasonable and true. If she is unprofessional, perfunctory or evasive in communication, then she may be suspected of fraud. We can also judge whether there are contradictions through many exchanges, such as whether the information she provided at different times is consistent.
We can seek the opinions of third parties or consult professionals to help us make judgments. If we have friends or acquaintances who have had similar experiences, we can consult them and listen to their suggestions. If conditions permit, you can also choose to go to a beauty shop for on-the-spot investigation, or consult financial institutions about investment issues.
When we meet a person who claims to open a beauty shop and invest in crude oil on WeChat, we can't easily conclude that she is a liar. We should judge her authenticity by verifying relevant evidence, knowing her situation in detail and observing her words and deeds. Be careful, don't trust the information provided by the other party easily, and protect your own interests and property safety.
