Three customers from Changzhou came to visit AE factory on Oct.11^th. All the three customers own modernized factory in Changzhou. Their aim is to be the agent of our product and develop AE series device into Changzhou. Furthermore, they want to help local government advocate new products and contribute to the environmental protection. Changzhou government has always been supporting enterprises on environmental protection and they also have sufficient financial resources to develop nearby market in Changzhou and Chekiang Province. They were deeply impressed by our AE series device and application in various fields. They believe that reasonable design and applications can well meet the need of market. They also showed the intention of cooperation and hoped we could achieve agreement on primary agency before Shanghai Industry Fair on Nov 4^th. More enterprises in Changzhou will be led to visit our device in Shanghai Industry Fair.
