The process of merchants adding live streaming accounts may vary from platform to platform. Taking the Douyin platform as an example, merchants need to follow the following steps to add live streaming accounts:

1. Register a Douyin account: First, merchants need to register a Douyin account. You can use your mobile phone number or email address to register.

2. Verify the merchant's identity: After registering a Douyin account, merchants need to pass the Douyin platform's verification to prove that they are a legitimate merchant. This can help merchants obtain more live streaming permissions and functions.

3. Open a Douyin store: Merchants need to open a store on the Douyin platform. Douyin store is an e-commerce function on the Douyin platform that allows merchants to sell goods on Douyin.

4. Bind Douyin store: After opening a Douyin store, merchants need to bind the Douyin store to their Douyin account. This allows merchants to directly display and sell goods during the live broadcast.

5. Apply for live streaming permissions: Merchants need to apply for live streaming permissions from the Douyin platform. The platform will review the merchant's identity, and once the review is passed, the merchant can conduct live broadcasts.

6. Set the live broadcast content: After obtaining the live broadcast permission, the merchant needs to plan their own live broadcast content. The live broadcast theme and style can be determined based on their own products, services, expertise and other factors.

7. Start live broadcast: After setting the live broadcast content, the merchant can start the live broadcast. During the live broadcast, the merchant needs to interact with the audience, showcase their products and services, and attract the audience's attention and purchase.

It should be noted that the live broadcast application and setting process may be different on different platforms, and merchants need to operate according to their actual situation. At the same time, during the live broadcast, merchants need to abide by the platform's regulations to ensure the legality and compliance of the live broadcast content.
