[QUOTE=Loren Pechtel;13497329]Exactly when do they expire?

I read it as one must enter *BEFORE* the stated date--in other words, they are not valid on that day. The travel agent reads it as they are valid on that date.

You need to entry before, At passport control in china they will ask you how long your stay is, If you are staying 5 days, & your entry is valid for only 3, they will remind you of that, & allow you to enter. Hotels check the visa enter dates, & copy that page & the stamped page for the police.
