Former business journalist Zeng Hang says it feels surreal when people call him an internet celebrity.

But that's exactly what he is.

The 30-year-old's Crazy Warfare Show, an online program introducing military knowledge using game-like computer animation, has attracted more than 700,000 subscribers on Youku.com, China's answer to YouTube.

"When I started the business, I only thought about how playing games could be fun and make a military-themed show unique," says Zeng.

"What I have yet to learn is how to manage so many fans."

The show sometimes uses clips created by viewers.

But most content comes from a group of program producers.

"It all started with one person," says Zeng.

"But it can't be a one-man show anymore."
