The China Railways YJ(跃进) design is based on China Railways PL2 class 2-6-2, itself derived from the JF6 2-8-2, the predecessor of the well known SY class mikado. According to Chinese sources a total of 202 locos were produced between 1958 and 1961.

At least two YJs are preserved. YJ 232 is at Baotou Steelworks, YJ 269 is at Diaobingshan, Tiefa, Liaoning.
