In celebration of International Women's Day, local authorities in Ningbo, East China's Zhejiang province invited 100 female sanitation workers to take free glam photos on March 7.

The activity, entitled "You Beautify the City and We Beautify You", was held at Zhishi Park.

Wei Bangyue has been a sanitation worker in Ningbo for seven years. This was her first time putting on lavish makeup and taking a glam photo.

"I have two children, one of whom is in school," said Wei, "I would never invest in a glam photo for myself."

The 47-year-old has always dreamed of taking a photo in a cheongsam. She asked her colleagues excitedly whether she looked beautiful in the dress.

Xu Xiaoya, a sanitation worker from Anhui province, took many selfies with her friends. She said that she wanted to capture the remarkable moment.

"Sanitation workers are hardworking and beautiful. They've been working hard to clean up the city. That's why we want to help them realize their feminine grace and beauty," said Chen Runwei, deputy director of the Ningbo City Environment and Sanitation Guidance Center.
