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?

No, ч is always soft(aka palatalized), regardless of anything. Russian transcription of Chinese is completely broken. Qin is spelt Тсинь, which is pretty far. There is no sound exactly like q in Russian. ш is Chinese sh, щ is very close to x (in Beijing dialect, at least), and there is no ч in Chinese; however, it shouldn't be a problem for you, as Russian ч is exactly English ch. :)
