I recommend not working for a training centre called Canpac, unless they've changed their name after fleeing the city without paying me.
Last I heard they were moving out to Heshan, wherever that is? The owner, a Danny K. Leung, will nickle and dime you and the students the entire time you're there, and at the end of contract he shorted me a substantial amount.
If they have changed the name, they will still be using the Can-8 machine, an antique computer system that the students all find boring.
