Is the future market in mainland China reliable? I’ve got scammed.

I am a victim of futures investment in mainland China. I usually do some stock investment occasionally. Recently, when I was trading online, I accidentally received their platform information introduced by the mainland futures salesman. He promoted the high-yield, zero-risk of their platform, saying that this is a good way to get rich. Although I have doubts, I can't help but got seduced by the profit temptations he sent me. So I deposited $70,000 and traded with the so-called analysts. It was profitable before. But in the next few days, everything is not the same thing at all. Few of my orders earned, and it earned less and lost a lot. It is not as good as the salesman promised.
I feel that something is wrong, but I still don't want to believe in myself. And after each loss, the mainland futures clerk and platform analyst will give me some promises, talking a lot of technical terms, and inducing me to deposit more. They said that if I increase the funds and increase the position, I can get more benefits and earn back the loss before. In this way, I invested a total of more than 170,000 US dollars, almost all of my savings are running out, I lost more than 100,000 US dollars, and more than 70,000 US dollars of trading positions have been locked. I have realized that I have been cheated and want to withdraw money. The mainland futures analysts were constantly urging me to deposit another $100,000 to get money my money back. He has said it several times in the same way. After I refused to deposit, the so-called investment instructor directly blocked me and kicked out the group chat. I am angry but helpless now.
