Sorry first posted this question as a 'reply'

Hi I am Canadian and am going to China in April. I plan on doing a 3 week tour of China and then go to Hong Kong and stay with a friend for 3 weeks. He will be taking me back and forth to China and showing me around. I know I would need a multiple tour visa. How difficult is it going to be to get for that purpose?They are valid for 6 months so should I get it now? Getting a little worried I may not get a multiple because I have never had a visa before and never entered China before
Thanks
