Mr. Liu is a large semi-trailer manufacture. Due to the requirements of "Safety Technical Conditions for Motor Vehicle Operation" (GB7258-2017) on January 1, 2018, purchasing demand is increasing. Every vehicle must be installed, which not only increases the cost of materials, but also the installation cost is rising.

Because Mr. Liu doesn't know much about the a Rigid Back Strip Brush device, and the existing supplier is also a small company, there is no special technical department, so Mr. Liu has repeatedly mentioned reducing the installation cost, and the supplier has no way to cope with it. Through the introduction of an old friend, Mr. Liu learned that there is a professional design, production and sales of Rigid Back Strip Brush in Guangzhou called Aoqun. After Mr. Liu found the customer service, he directly explained his intention to reduce the installation cost through product improvement. The customer service provided a professional solution within 4 hours and sent samples within 3 days.

Mr. Liu started the trial installation after receiving the samples of Rigid Back Strip Brush, and the installation efficiency was indeed improved by 30%. To this end, Mr. Liu also signed an annual supply agreement with Aoqun, making Aoqun his long-term stable supplier.
