hi i am philippine passport holder, i have an tourist visa only, can apply an temporary residence visa and stay in china for few months?

i want to stay in china for few months, because my boyfriend is chinese, his family want to meet me, and they ask me to live with them so they can know if they can agree that their son will marry me, what is the best thing i can do? i can apply an temporary residence visa even we not get married?
Thank you
