Jianshe Jianshe and Yamaha have formed a joint venture to produce motorcycles - Jianshe Yamaha, which produces domestic motorcycles with Yamaha trademarks such as Tianjian, Tianji, Xunying, Fuxi, Qiaoge, E8, The I8 and others are all their products, but construction does not mean building Yamaha. Construction does not involve the joint venture. Some of its models use Yamaha technology, but they cannot be called Yamaha, and the quality is not as good as Yamaha's products. Moreover, there are many no-name cars that use Jianshe's trademark or are sold under the banner of Jianshe. The quality of these cars is very poor.
