BRUSSELS, May 2 (Xinhua) -- A group of Belgian students walks through a greenhouse on the outskirts of Chongqing, China, where fields of tender seedlings stretch out beneath their feet. Leading them is Francois Serneels -- a Belgian agronomist affectionately nicknamed "Dr. Bethune of Potato," after the Canadian surgeon Norman Bethune who became a hero in China for his dedication to the Chinese people's fight against Japanese aggression in 1938.
