What specific threads there discuss redeeming award flights on MU using DL miles?
You can check their Skyteam Threads that includes Delta. But I searched a few posts and found they were also saying very hard to use DL miles to book MU flghts.
I remembered DL used to able to redeem 7.5K for domestic first class on MU/CZ/MF, and 6K for economy. Yes, 7.5K only for FC. Maybe since they fixed this, MU award space became limit. Old good days are gone.

You live in Shanghai, well you can just call DL's Mandarin line for MU award space.
