Visa application bf as the sponsor

Good Day!
I would like to ask something prior to my plan on getting a visa application in China.

My boyfriend is taking me out on a trip with him in PRC and he will be the one to shoulder all of our expenses regarding our trip. What additional requirements should I submit to have my visa approved? He is a Spanish citizen and will be flying to the Philippines on October 5 and we will be leaving for PRC at the same time on October 15, 2016. Should I attach his passport copy and bank statement too? I have a complete list of requirements already but except for my bank statement I would be submitting my Certificate of Emlloyment. I will be more than grateful for your response on my query.
