Is it accurate to predict stocks with plum blossom easy number?

1. Since the opening of the China stock market, many people have tried to use the Book of Changes and gossip to predict the rise and fall of stocks, and some special books have been sold, as well as some special websites, gossip prediction software or special forums. As far as I know, so far, there is no recognized and systematic method of Yijing gossip that can accurately predict the rise and fall of the stock market to a practical level of more than 50%.

2. Excuse me: If you have a method that can track the rise and fall of stocks very accurately, will you make a name for yourself publicly or "make a fortune silently"? !
