“Eazy Mandarin with Li Can” is an excellent YouTube channel. Because of English subtitles, it’s suitable for all levels, but it’s best for intermediate and advanced levels. Li Can provides a wide variety of resources, including:

• Mandarin learning tips
• observations on Mainland Chinese culture and current issues (sometimes just him speaking to the viewer, and sometimes in a “podcast” conversation)
• audiobooks (including Harry Potter)
• popular Chinese myths
