With the help of the Hubei Charity Federation and China Railway Wuhan Group, 300,000 facemasks, 90,000 alcohol disinfection tablets and 2,000 bottles of liquid soap were transported to Wuhan on Jan 21.

"These fans are from all walks of life. Some helped contact facemask factories overseas, while others, who are medical professionals, helped contact hospitals in Wuhan. They are very efficient, devoted and offer help unconditionally," Wang said.

A fan from Guangzhou, capital of Guangdong province, who joined the donation drive, said: "One of the fans is a Wuhan native. She shared details of her life with us, such as persuading her parents to wear facemasks and staying at home to avoid possible infection. When an ambulance comes to her neighborhood, she is worried. She is terrified and all of the fans in the group tried to comfort her, though many of us have never met.

"Fans are a community devoted to our idols... We also play a role when disaster happens, like the ongoing viral outbreak," she said.
