After waiting more than three hours in a TV studio near Beijing's Fifth Ring Road, I finally got to meet Wang Zhenyu, deputy mayor of Linfen city, Shanxi province.

Wang had just finished delivering his business pitch on The Impressive Scenery of Shanxi, and he was still full of adrenaline. "I was nervous, very nervous, trying to remember my speech all the time, including when I was standing by," he said.

"But now, I've forgotten everything. My mind has gone blank," he added, with a laugh.
