Tchan-Tia-Kou Sailplane Works
Shen Yang, near Mukden
Quantity production of Polish designed ABC, Bocian, Jaskolka and Mucha sailplanes began at Shen Yang in 1955-56. At about the same time, a design team was formed under the leadership of Dipl./Ing. J.Niespal of the Polish SZD (experimental glider establishment).
The first product of this team, which included Dipl.Ing Tchen-Kuei-Wen and Li-Ti-Tiun, was the Lie-Fang No.1.
