Invitation Letter from My dear friend (Chinese citizen)

My friend from China had visited me twice in India. And Now I want to visit her. For her Indian was not a big deal very easy. but Chinese tourist visa is very hard enough i guess.
Can you tell me How can my friend help me to get it without showing the day by day itinerary of hotel booking.
She is Chinese Citizen in Nantong, Jiangsu Province.
She needs to send me an Invitation letter.. and also her bank statement? so that I don't need to show hotel booking itinerary day by day as per requirement by Chinese Embassy.
Because I will live in her home with her whole family.
Please suggest me, And this is my first time going to Abroad.
Thank you.
