I find this a very disturbing story.   Why are they in jail?   Is it for underpaying duties? (That is yet to be proven.)  Even if they did underpay, the most they should get is a fine.   And they shouldn't spend a year in jail without even a trial.  Furthermore, with a 99% conviction rate, China cannot claim to have a fair justice system.   These people are screwed, as far as I can see.   I think Canada should do whatever we can to help them.
