I recall some talk about this but searching didnt find the right threads, so lets re-ask.
Expired Canadian Passport has a 3 year China Visa glued inside it 2 years validity left.
New/Shiny Canadian Passport is now on hand.
Can I go into China with both passports and get thru without hassle?
Do I need to get a new China visa for the new pport?
I also recall someone talking about steam and reglue - I cant recall if that was serious or a joke...
