First, Changhe is a wholly-owned subsidiary of BAIC, but it does not appear among brands or subsidiaries on the CCF Forum homepage.
Second, it was merged with BAIC Weiwang brand in 2017 but that brand seems to have gone belly up. And as for Changhe itself, we haven't seen much activity here regarding it lately.
Third, it has a new, and very unique/unusual website.
I have attached a screen shot of it. But don't give up too quickly it has some interesting stuff (in Chinese) deep in its innards.
As an alternative, if someone would like to see what models they have available, they had better go to the global website: www.changheglobal.com
. But even it is not comprehensive in the available models.
Fourth, for pronunciation purposes, a pinyin rendering as, Chang'he, instead of Changhe (sometimes confused with Change) is helpful for improved accuracy, much in the same way as with its previous parent, Chang'an (aka Changan).
