Shanghai diaries

Another recent documentary series, The Untold Story of 221, has been jointly produced by the Qinghai radio and television bureau and the Shanghai Radio and Television Documentary Channel. It turns its focus on China's first nuclear-program base (No 221) in Jinyintan, Qinghai province. It's where China's first atomic and hydrogen bombs were developed.

It elaborates upon the establishment story of the former factory, the development of the atomic and hydrogen bombs, and the site's later transformation into a tourist site.

The three-episode series premiered on Dragon Television on Sept 27.
