You have to think about how 300 thousand came from. If 300 thousand comes from foreign exchange, then you should continue to engage in foreign exchange. It shows that you have a strong ability to do foreign exchange. If 300,000 yuan comes from physical business, then we should continue to do physical business.
My suggestion is to do what you are good at according to your own ability. Doing foreign exchange immediately without doing foreign exchange is like doing business immediately without doing business. No matter what you do, you should start from a little bit. You can't invest so much money in the first place. Slowly develop. Do what you are good at.
If you are not good at anything, you might as well save your money first. Earn wages by working honestly and learn to improve yourself. Wait until you are good at something.
Of course, the problem between you is neither foreign exchange nor business, but mainly communication. So please see a psychiatrist to find out the communication problems.
