ChangHeng's target audiences are in scale models. To better service people from different hobby groups, ChangHeng starts from importing completed range of model trains to variety of models in general. Retailers shops need support immediately rather than back and forth internationally, so ChangHeng plays an important role between manufactures and their dealers. No matter on introducing and demonstrating new and existing products or instant technical support, ChangHeng is always there for them. A successful business needs co-creation of value with their partners.
