Mr. Lu is an installation personnel of the screen door, because his company has cooperated with AOQUN for many years, and the business with AOQUN is also very familiar. Mr. Lu said that the hole position of the shield door back strip brush holder of their company is round, so there will always be errors when the door is aligned, so that their installation efficiency cannot be improved.

AOQUN salesman J went straight to Mr. Lu installation site and found that the assembly principle of the shielding door seal back strip brush was similar to the escalator safety back strip brush, so J immediately suggested that the design section applies to change the hole position from a circle to an ellipse. And after 2 days, he also actively trial-produced a product with a circular hole pitch and a close aperture to give Mr. Lu a trial installation. As a result, Mr. Lu was very satisfied with the ease of assembly and reported the proposal to the company for optimization.

Two months later, Mr. Lu called to say that because of AOQUN professional guidance, the screen door back strip brush optimization program was confirmed by the company, so that his salary application was approved.
