Can we visit 2 time under visa free program?

Hi there, Im a Canadian passport holder. Wanna make sure,
Will I get 01st times entry in Beijing for 03days & then about 02 months later for 02nd time in Shanghai for 02 days while I'm returning from Bangladesh Dhaka? My traveling route like this
[Toronto - Beijing (03 days visit) - Dhaka]
after 02 months later
[ Dhaka - Shanghai (02 days visit) -Toronto ]
Thanks.
