Mr. Ji received the government's project for sewage treatment of aquaculture fish ponds. This project is the first experiment. After a long period of design, modification, and determination, it has taken up most of the time. Seeing that the project acceptance time was about to come, Mr. Ji urgently needed to find a filter brush for aquariums processing factory that could cooperate with fast delivery and provide 15,000 filter brush for aquariums within 10 days.

Mr. Ji saw that Aoqun is a professional filter brush for aquariums processing factory. He contacted the sales department Miss Liu with a try attitude, and went to talks to understand Mr. Ji's demands. In order to eliminate the transportation time, all products must be completed within 7 days. In order not to delay the customer's construction period, a contract was signed with Mr. Ji and communicated with the production department on the same day. Combined with the current production capacity, two fully automatic filter brush for aquarium machines worked together in two shifts. Delivered the goods to the customer in advance.

After receiving the goods, Mr. Ji immediately installed and used it, and completed the project as scheduled to avoid liquidated damages caused by the delay. Mr. Ji sent a message saying "Thank you very much for your full cooperation. I will still ask you to do other projects. You are really a professional and efficient filter brush for aquariums processing factory."
