The last two by littlelittle are Millipedes (Myriapoda) - Glomeridae
The first images by littlelittle and the one by lsp380 are Woodlice (Isopoda: Oniscidea), but certainly not Armadillidium. I think they are two different species, but certainly both in the family Armadillidae (not Armadillidiidae, like Armadillidium).
I don't know the Asian species so I have to be very careful. Maybe these can be found in the genera Dryadillo, Sinodillo or Spherillo (all present in Eastern China) but it would seem that many Asian species are still in "Armadillo" (or even "Venezillo" ?) - note the quotation marks - meaning that the genus name is probably plain wrong, but needs revision.
As I don't know the Asian Woodlice I wouldn't want to hazard a guess for the species or even the (current) genus.
