These YOUNGMAN trolleybuses are called "JNP-WG120G"?
The BJD-WG120N2 in Beijing has a sign of "JNP-WG120G" on the dashboard screen; but it's "Hyayu BJD-WG120N2" on the vehicle plate.

Beijing is a special situation, basically a deeply customized model based on youngman, jointly developed by Youngman and Foton, so the model is Foton brand

It is said that some of the prototype trolleybuses in Beijing have 2 plates: one from Hyayu, and one from the original manufacturer (FOTON/YOUNGMAN)?
(Also, it is said that the model signs on the 2 plates are different from each other; not sure about that, someone else told me)
