I'd like to think my Mandarin pronunciation is generally pretty reasonable, but I often get tripped up with X and SH - for example words like 雪 and 水, or 虾 and 莎. Even with different tones, I find these kind of tricky to get right - although obviously context makes the meaning more obvious.
Does anyone have a good tip on how to clearly show the difference in the X sound vs the SH sound? What shape should I have my mouth, and where should I put my tongue for each of these sounds?
