I can’t figure out how the mouth shape should change as it changes from lü/nü to the “e” sound. I couldn’t find an explanation for that in the pronunciation guide here either: https://chinesepod.com/tools/pronunciation/section/15
I’m having the most trouble with the “l” in lüe. Where should the tongue be placed when trying to pronounce this word? Can I see a video of someone pronouncing these sounds, please?
