I have been to Canton Fair for several times, here I'd like to share my experience with you:

Canton Fair is a large-scaled trade fair, where the participants should be well-prepared to handle all kinds of unexpected difficulties.

I  suggest:

1> find your target customers who are exhibitors at the trade show, and fix a time with them before the exhibiton.

2> find out the detailed information about each hall of the Canton Fair you will participate in, including the location, time, and traffic guide.

3> find an experienced interpretor for your business negotiation.

Good  luck!

Happy Middle Autumn Day!
