China had more than 241 million people aged 60 or above by the end of 2017, accounting for 17.3 percent of the total population at the time, according to official statistics.

It is estimated that the country's elderly will occupy about one-quarter of the population by 2030.

But the shutterbugs are showing their enthusiasm in embracing their youthful life-carrying heavy equipment on their trips to take pictures and staying up late to process their work.

"Many senior citizens have changed a lot after taking up photography as a hobby. They told me that they found a way to realize the value of life," Luo Shirong, a salesperson at a photography equipment store in Hefei, capital of Anhui province, says.

In recent years, Luo saw more and more elderly people buy equipment, accounting for nearly 60 percent of the store's sales.

Senior citizens in Shenzhen, South China's Guangdong province, were the most active clients of online camera shops, according to Alibaba.

"Many older people followed their offspring by moving to a new city, leaving their old friends and neighbors behind. Loneliness became one of their biggest challenges," says Zhang Zhixian, 72, president of the Shenzhen photography society for the elderly.

"Photography helps them share a common language with others," Zhang says.

Founded in 2006, Zhang's photography association now has more than 1,400 members. Every month, the members take pictures of local senior citizens for free.

"We find joy in photography, and pass it on to others," Zhang adds.
