Keep-inspired Chinese workout course website

Build a Chinese “workout course” webpage inspired by [reference_brand_en]: include a full-screen athlete hero image, transparent sticky navigation, Chinese capsule-tag categories, and a grid of Chinese course cards. Each course card corresponds to a training program; use the course styles of creators such as [instructor_examples_en] as references to design Chinese titles and labels for difficulty and duration. When clicking a card, open a course preview video player within the page that strictly matches the card information. Overall, keep the design minimal yet detailed, using smooth scrolling and hover animations, soft gradients, and refined typography to create a high-end Chinese experience. Use Tailwind CSS to implement a fully responsive layout.
