Zhenghe County is a county of northern Fujian province, People's Republic of China, bordering Zhejiang to the north. It is under the administration of the prefecture-level city of Nanping. The Min-Bei dialect, or Northern Min (Guing'ei Di) prevails in Zhenghe County.
Zhenghe became a county in 1000AD, but its previous name is Guanli . In 1115AD, the emperor appreciated the Gongfu tea from Guanli County. He delightfully named the county after his reign title "Zhenghe", which lasts till now.
