Intermediate | Yellow Mountain

From a channel Lumen includes in full: Nearly every upload is a structured Mandarin lesson labelled by level (Newbie to Advanced). Each lesson presents a dialogue, translates it, and explains vocabulary, grammar, tones and character components, as the transcripts confirm (hzMDBUHSw48, AnKUEIjcoBg, KfEDybk7Wx8). The only non-teaching uploads are a few site-navigation and product tutorials such as nZVp6dmmRDA, and these can be caught by title patterns. Titles are descriptive and contain no clickbait.
