Where do I get my visa since the Houston consulate is closed?

My fiance is Chinese, lives in Chongqing, China. I live in Texas. Where do I got to get a possible visa for me to go to China, meet my fiance's parents/family, ask them for permission to marry her, and then we get married and live in her city? She is planning on coming here for us to meet, since all plans were cancelled due to the covid virus. She is going to write-out her invitation letter for me to hopefully get to China for us to marry.
