On Saturday, hundreds of people were still busy completing their work at the Beibei fire scene, where they monitored the ashes and cleared rubbish from the mountain in temperatures that were still above 40 C.

Cheena joined a local volunteer group of 60 people in the morning to carry water up the mountain for the firefighters and volunteers guarding the fire sites.

Wearing a yellow vest and a towel soaked in water on his neck to keep cool, Cheena worked for about six hours carrying water in a large backpack. He was deeply impressed by the efforts of local residents.

"I met people who are not so keen on outdoor life, and who are not that athletic, but they all took part in the rescue effort and did their best to help," he said.

"It was pretty amazing and kind of surprising for me to see so many young volunteers."

A French motorcyclist, named only as Jeremy by local media, carried fire extinguishers, water and medical supplies up the mountain.

"I have been here day and night for three days," he said in a video on the Douyin social media platform on Friday. "I go home and sleep for four to five hours and then come back."

The Frenchman, who has been in China for about nine years, lives in Beibei. He likes to hike on Jinyun Mountain with his family, and told local media the mountain is like an old friend and he hopes it can recover from the fires soon.
