As long as China's economy develops at a high speed, the stock market will not crash. The adjustment range of 10-20% is normal. Exercise your mind. Don't worry. I estimate that I lost 10 thousand yuan today, but I believe I will pay it back twice in the future. The adjustment time may not be short and the range will not be small. Real risk education, trusting your fund manager, keeping a correct attitude and holding the fund for a long time will still bring you rich benefits.
