WeChat group owners are free to introduce themselves, such as:

More formally, I can say: Dear friends in my group, I am very happy to be your group owner. I am honored to join this group. I hope the friends in the group will give me opinions and suggestions when I am the group owner, so that I can gain a lot in the future. Thank you for your support and help.
