Chen, a nurse at Renji Hospital affiliated with Shanghai Jiao Tong University School of Medicine, signed up for an emergency medical team to help Wuhan in Hubei province battle the COVID-19 breakout.
That meant the couple had to delay their wedding ceremony scheduled for Spring Festival, and a three-month separation for the love birds.
"We knew it was going to be hard but it was just the right thing to do," said Chen, who completed her 14-day quarantine and tested negative after her return to Shanghai in mid-April.
The hospital showed its appreciation by organizing a mass wedding on Friday to help the couples commemorate their love as well as selfless contributions.
The group ceremony was held at the historic Waldorf Astoria Shanghai on the Bund, in a room decorated with ribbons and bouquets and attended only by close family and friends as social distancing is still being advised by authorities.
"Almost three months ago, the brides put on white nurse's uniforms instead of white bridal veils. Now that they are back safe and sound, it's imperative that we host a ceremony for them," said Xia Qiang, Party secretary of Renji Hospital.
"I hope they learn to respect, tolerate, understand and support each other after what they have experienced in Wuhan and through this special experience at the start of their marriages," Xia said.
Gao Yang, 29, promised to do all the domestic chores in the future. He said Wuhan had given him an insight into how intense his wife Zhang Lin's job was.
Hotel general manager, Richard Saul, said: "We are proud to offer a historic venue and dedicated services that bring memorable sparkle to the medical heroes' most significant moment in life. We want to express our sincere gratitude to these true heroes who protect and save people's lives with selfless efforts."
