The procedures and steps for opening a Douyin store are as follows:

1. **Register and log in to a Douyin account**: First, you need to register an account on the Douyin platform and log in.

2. **Complete real-name authentication**: Find three neat horizontal lines in the upper right corner of the "Me" page and click on them, then find the "Settings" option and click to enter. In "Settings", first open "Account and Security" for real-name authentication. Real-name authentication is a necessary condition for opening the showcase function.

3. **Meet the opening conditions**: After the real-name authentication is completed, you need to meet the following three conditions on Douyin to open the product showcase function: the number of fans is greater than or equal to 0, the number of published works is greater than or equal to 10, and these works should preferably be original and related to the product.

4. **Apply for opening the product showcase function**: After completing the above conditions, you can click Apply Now, enter your mobile phone number, WeChat account, select product categories and other information, and then submit the application.

5. **Waiting for review**: After submitting your application, your account will enter the review stage. After the review is passed, you will receive a message notification.

In addition, if you want to open a Douyin store, the process will be slightly different. First, you need to search for "Douyin Store" in the browser, click "Sign in Now", and then enter your mobile phone number to receive the verification code to log in. Next, choose the theme type for opening a Douyin store, which can be a personal store, individual business owner, enterprise or cross-border e-commerce. Then, you need to upload information such as business license and ID card, and make sure that the uploaded ID card information and the operator of the business license are the same person.
