Trial Lesson Feature

The "Trial Lesson" feature of the LOL Online Learning Platform is a resource display module specifically designed for educational institutions. It allows administrators to upload and present course-related videos, images, and documents, enabling visitors and potential students to preview content before enrollment. This feature not only enhances marketing and teaching demonstration but also serves as a preliminary guarantee of teaching quality. Trial content is showcased in the "Trial Lesson List" on the homepage, supporting multimedia playback and YouTube embedding to increase presentation flexibility and marketing effectiveness.
