According to the official website of Emei Mountain Ski Resort, it does offer single-board (also known as monoski or one-ski) options for skiing and snowboarding. In addition to double boards (standard skis/snowboards), they provide equipment rental services that include single boards specifically designed for beginners or advanced riders seeking new challenges.
Please note that availability may vary depending on the season, weather conditions, and other factors, so it’s always a good idea to check with the resort directly for the most up-to-date information.
