Cheng Han
The Irwin mango was first grown in Taiwan in 1962 by Cheng Han-chih (鄭罕池) in Douliuzai Village, Yujing District, Tainan. In 1973 the government designated Douliuzai Village as a mango special agricultural zone. By the 1970s the residents of Douliuzai Village were known for their wealth due to mango cultivation. Cheng Han-chih is considered to be the godfather of Taiwan's lucrative modern mango industry. Irwin mangos have been the most popular mango in the Taiwanese market for fifty years.
