шь & щ

[ugly-boy.livejournal.com]

Are шь and щ the same? Also, is this analogy correct:

щ : ш :: тщ : ч

Does the sound "тщ" (presumably as in Mandarin q) exist?

"Щ" is rather a long and soft form of "ш". "Ш" itself is hard. Even as "шь" in e.g. "лишь", "спишь" etc. "Ч" is close to "тш" and is always soft. But I'm not a linguist. Just in case you need an urgent answer :)

Nah, nothing urgent, I was just curious.
