  2. About Wenzhou Medical College

    Wenzhou Medical College

    Wenzhou Medical College, designated as a key university in Zhejiang, is an institution of higher learning under the leadership of Zhejiang Provincial Government. Its history can be traced back to Zhejiang Specialized Medical School established in Hangzhou in 1912, named "Zhejiang Second Medical College" at that time. In August 1958, part of Zhejiang Medical College was moved from Hangzhou to Wenzhou and began recruiting 5-year fulltime program students, hence the name Wenzhou Medical College (WMC).
