1. A contract must be signed before the Douyin transaction. Although the Douyin account is a virtual product, it is also protected by law. Only after signing a contract can you protect your rights through the contract when problems arise.

2. During the transaction, you must carefully confirm the account information. For example: what is the positioning of the account, whether there are zombie fans, what is the background playback data, whether it is restricted, etc. All of these must be understood clearly before trading. So as to avoid unnecessary trouble at that time.

3. After the transaction, you need to change your password, bind your mobile phone number, email address and other information. If it is a corporate account, you also need to change the account operator. Both certified personal accounts and corporate accounts are at risk of being retrieved, so you need to find a reliable platform for trading.
