Is there a chance I get a tourist visa with a length of a month and a half

Im visiting my fiance from January 12- March 01 2016. I believe L type is the most suitable visa for me since we are not married until April 2016. Is there a chance it will get approved considering Ill be staying there for a month and a half?

This is my 2nd visit to China. I've been to China back in October 2015
