Tax investigation in the country is now extremely frightening. I was planning to watch the market today when I suddenly received a call. It turns out a friend was detained when leaving customs. I made countless calls to rescue him, and finally found out the reason was trading US stocks. The tax authorities monitored us through big data, and the final result was that we had to pay an additional 3.5 million in taxes, along with a bunch of documents, such as proof of no criminal record and others.
