If you know the name of the company, you can enter its name on Baidu to find out what the relevant information is. But a better way is if you can know the English name of the company, and then go to www.google.com to check the company's information, or find the company's website to browse, so much the better. But only if you have good English, or find someone with good English to help you. Of course, I assume that the foreign company you are talking about is based on English. Generally speaking, if you are a liar or a small investment company, it is very likely that you can't find any relevant information at all, or you don't have your own website, or even if you do, it is very simple. In this case, I think you need to be vigilant. If the company can have more content and information on Google, and its website content is relatively sound, then the possibility of fraud is less. In this regard, you can do some simple surveys.
At the same time, you can also contact the company and ask for some information about their company. I believe that if they are willing to cooperate with you, they will be happy to provide it. You can look at their information, history, and so on to understand their background. At the same time, see if the information they have prepared is credible, or just glance at it.
Just curious, is that company American or somewhere else?
Furthermore, if it is an American listed company, it must have an annual report, which can better reflect the company's strength and operating conditions. Generally, it can be obtained directly from the company or downloaded from the company website.
I wish I could help you in some way.
