Mr. Deng Xiaoping wrote down this:

Established on December 6th, 1984 upon the approval of the State Council, the Tianjin Economic-Technological Development Area (abbreviated as TEDA and transliterated as Taida) is one of China’s earliest national-level development zones. During an inspection tour to TEDA back in August 1986, Mr. Deng Xiaoping, the chief architect of China’s reform and opening-up, wrote down this: Development Zones Are of Great Promise. More than three decades later, TEDA has grown into a national-level development zone with various sub-zones boasting the biggest economic scale, high-level alignment with global standards, and the best comprehensive investment environment in China.
