I am a gold practitioner and have interviewed many investment companies in Guangzhou. As far as I know, many investment companies in Guangzhou are informal, especially those engaged in foreign exchange and gold.
Of course, there are also legitimate companies, but most of the brokers of such companies have no or low basic salary, mainly based on commission. Don't be embarrassed to ask about the treatment. If the company is transparent in this respect, it will tell you. On the contrary, if you are vague about the treatment and try your best to avoid it, there may be problems!
If you have any questions, you can come to me. Helping others is the foundation of happiness!
