Is CINDA Futures safe?

In this June,I receive a friend request in a stock-exchange group,the peer shared some experience on stock trading with me and told me to share good stock together.I had a good conversation with him.After a month,he told me that he had made some profits by a teacher’s instruction.Then I was pulled into a group,in which I have observed for some while,finding that there was a teacher named Mingxuan Luo teaching on stocks and recommending stock,which I found was really good.In the middle of July,Luo began to induce futures to us, saying that the market is good, and advise us to grasp the trend.Then he pulled the salesman of CINDAFutures into the group and asked us to open account in it.He said to take us to make money together.In the next week,many members sent their screenshot of profits,which overweighed my profits.Having thought overnight,I withdrew my fund in stock and deposited 600000 RMB into CINDAFutures.I have planned to recover part of my losses in stock,while I made a loss of 300000 RMB within 3 days.As long as the teacher instructed me to operation for the cocking market,the market would do down.I had a sleeplessness,felling something was wrong.
