Notes

1. Cookie Validity Period: WeChat cookies have a relatively short validity period, so it is recommended to check before each use
2. Publishing Frequency: It is recommended to control the publishing frequency to avoid being identified as abnormal behavior by the platform
3. Short Title: The system will automatically generate a short title of 6-16 characters from the main title
4. Number of Topics: It is recommended to add 3-5 relevant topics
5. Original Content Declaration: Checking the original content option must comply with the platform's original content specifications, otherwise penalties may be imposed
6. Collections: If the account has collections, the video will be automatically added to the first collection
