I am planing on getting married in china

My fiancé and I are planning on getting married in China I am a Canadian citizen and she is a Chinese lady. I am trying to find out what documents I will need to bring with me when I go to China. I have been widowed two years ago and I am unclear what documents I need to bring with me. Can you tell me exactly what I need to bring, or where I can go to find out what I need to bring with me to get married in China?
Thank you in advance for your assistance.
