You can't. The homepage setting of litchi micro-course is biased towards mode. Only one topic, one column and one course can be added to the home page, and the order cannot be adjusted, and the titles of columns and courses cannot be modified. Litchi micro-course is a platform dedicated to public knowledge sharing, and all functions of the whole platform are free to use for life. Here, you can share the class anytime and anywhere, and you can also study in class.
