To participate in investment and financial management, you must have a plan and have your own opinions. The technical guidance of securities firms is only to help you improve and give you reference, but you are the final decision-maker, so remember to know your own gains and losses at any time, adopt them when you can, resolutely refuse to adopt them when you can't, maintain your independent judgment and safeguard your own interests. Companies like this will teach customers this way at the beginning of cooperation. I hope you can remember them and learn to recognize them.
