Qin records her life and writes about her feelings in her posts on social media. In one post, she wrote: "After retirement, I had nothing to do but eat three meals a day. After my parents died, I was depressed and felt like I had no one to talk to anymore."

About two years ago, she and her husband moved from Liuzhou to live with their son in Shanghai.

Since her son helped her sign up to social media accounts and taught her how to post and communicate on those platforms, Qin has been sharing her daily life, especially her personal style, which caught the attention of fashion enthusiasts and led to her being featured on magazines and appearing at fashion events.

All this seems to have opened the door to a new world, says the physician-turned influencer, who is happy that people from all over the world have left her comments and likes, and that they appreciate her outfits. "I hope more people will see me, a 70-year-old woman from China, who likes to wear Miu Miu and Prada," she wrote in one post.

Huang says: "I just wanted to let her have fun with social media. I take her out and take photos of her, and gradually she began to enjoy social media."

Qin's posts often feature her wearing brightly colored outfits, high heels and eye-catching accessories. As she says, during her decadeslong career as a doctor, she only wore a lab coat every day, but she still loves matching white with different colors.

She also dresses her hair in different styles, such as long braids, a tight bun or leaves it loose and decorated with a neat bow.

"My husband once took a business trip to Shanghai during the 1980s. He bought me lots of dresses. When I wore the outfits around my hometown, people's feedback was varied," Qin says. "Nowadays, aesthetics of beauty are quite different and diverse. I am glad that I can wear whatever I like and pursue beauty at 70."
