Sharing China's heritage at Osaka Expo

Heartbeats sync and stories unfold as volunteers bring a shared human spirit to life at one of the world's biggest cultural gatherings.

Dong Weiqian was only 8 when the Shanghai World Expo was held in 2010.He didn't get the chance to visit — and has always regretted it.

Over the years, he closely followed the 2015 Milan World Expo and the 2020 Dubai World Expo, and attending the event became a dream he was determined to fulfill.

"I've always loved connecting with people from different backgrounds," he said. "I believe these interactions allow me to see the world from perspectives I might never have considered otherwise."
