Brazilian with issue Business Visa Valid until 2018 - traveling on leisure

Hi, I'm brazilian and I've obtained a Business M type earlier this year to visit my employeer branches, since as per the Chinese-Brazilian agreements I have the right to do multiple entries, I'd like to know if I'm also entitled to travel on leisure (tourism) with this entry permit or if I must request a new one.

Thank you,
Kind Regards,
A. Silva
