1. Authorization: You can sign an authorization agreement with relevant personnel to authorize them to conduct securities trading on your behalf. This way can clearly define the trading authority, term and responsibility, and ensure the legitimacy and security of the transaction.

2. Personal guidance: If the other party is a novice or unfamiliar with the operation of securities trading, you can personally guide and educate them to help them learn and understand the basic knowledge and rules of securities trading operation.

3. Exchange and cooperation: We can learn and discuss from each other, share trading experience and provide necessary help and support. This way, the other party can gradually become independent and have the ability to trade independently.
