Hello @100355143021654 ...

I am not sure if you meant to post your question here or not.  You've posted your question in the global Canvas Community website.  People from all over the world come to this site to ask questions about the Canvas LMS (Learning Management System), join various groups, check out written and video tutorials, read about new features coming to Canvas, and much more.  When you say you want to be an "English online Instructor here" and "want to create online courses here", I'm not clear on what you mean by "here".  Within this website, you cannot create online courses.  However, there is a free version of Canvas that you can use called "Free For Teacher".  You can create a FFT course by following this link: Canvas LMS for Higher Education | Product and clicking on the "TRY CANVAS FREE" button.  I'll also direct you to a FFT area within the Canvas Community which might be of help:

Free For Teacher Canvas Users - Instructure Community

Finally, this set of videos might be good for you to review:

• Canvas Overview (Instructors) - Instructure Community - 384268
• Canvas LMS Tutorials for Online Teaching - YouTube - This is a really good playlist of tutorials from a fellow Canvas user.  Videos are a couple years old, but most still apply.

I hope these resources will be of some help to you.  Sing out if you have any questions...thanks!
