Jiang Dezhang, 27, and 26-year-old Tie Guangju both sat on wooden boards supported by ropes and pulleys.
"Our wedding was both romantic and like our daily work", said husband Jiang.
Also suspended with the couple were the best man and the bridesmaid who were work colleagues.
The couple exchanged rings in the air and hugged and kissed each other as the wedding guests and passers-by cheered below, reports Yunnan Daily.
As the couple were exchanging rings a scroll came down from the top of the building with the words "High Altitude Love" written on it.
