What should I do after being cheated? 1.5 million was gone in wake of adverse recommendation.

In July 5, someone added Mr. Wan through Wechat. At first he thought it was one of my friends and passed the request. He learned through chat that this netizen is doing financial investment. Recently, she invested in Xinghe Security and earned more than 300,000 RMB a month. She said it is a good way to make money and wanted to invite Wan to participate.At first Wan didn't believe it and paid no attention to her. Later in a long time, this netizen kept sending posts of traveling, food, etc., in Wechat moments. She told Wan that the reason for her traveling everywhere is the money she earned through investment, Occasionally, she would also send he some screenshots of making money. She has a tongue in her head. They became friends unconsciously then. Later, she invited Wan to join in the investment of Xintouzaixian. He agreed and invested at the very day. She then invited he to a group, where there is an investment advisor who teaches everyone how to operate. Many people in the group said they are making money.This netizen helped Wan to follow the instructions of the advisor. As a result, he earned a few at first. The advisor said that everyone’s funds for the operation are not up to the requirements. He wanted to help everyone earn 300,000 RMB a month, which requires at least 300,000 RMB deposit for each person. And it is expected to double in one month. Many people in the group believe in the advisor and added the fund.Seeing so many members joining, Wan also followed.Unexpectedly,there was a forced liquidation because of teacher’s order recommendation. Wan has made all losses within these days.
