Viewers have been hooked to Charm China since it was first aired on China Central Television on July 14.

Each episode of the show compares cultural elements and economic development in two different cities, giving a chance to local government officials and residents to voice their views on TV and become somewhat famous in the process.

In addition to knowing their cities very well, the mayors or deputy mayors who appear on the show also need to be eloquent. Sometimes, they are asked to join in the singing and dancing.

Others who appear are members of cultural troupes and chefs. Some celebrities also choose to back their preferred cities or hometowns on the show.

Xu Peidong, an established songwriter, has visited Yan'an, Shaanxi province, to create works related to the city that is considered the cradle of the Communist revolution in China.

He participated in the debut episode of Charm China that featured the city.

"The food there is also highly recommended," Xu says in a recent interview. "It is delicious and once fed pioneers of the Communist Party of China."

"Yan'an is getting more fashionable," he says. "While young people there have not forgotten the city's original spirit, they are catching up with the times."

He says that the positive energy of youth is reflected on the show.

Yan'an's "competitor" in the same episode was a place with its own characteristics: Alxa in the Inner Mongolia autonomous region, which is famous for its roasted lamb and desert scenery.

Liu Wang, an astronaut with the Shenzhou IX spacecraft, decided to back the city on the show because some Chinese manned space missions have been launched there.
