Mr. Lu did the installation of the screen door body, because his company has cooperated with Aoqun for many years and is very familiar with the business of Aoqun. In the spare time of receiving goods, I heard Mr. Lu complained that the holes of their company's door weather strips brackets are round, so errors often occur when they are aligned with the door body, so that their installation efficiency has not been improved.

After listening to Aoqun’s business, he did not respond to Mr. Lu’s complaints in person, but went straight to his installation site and found that the assembly principle of door weather strips is actually similar to that of escalator safety brushes, so he immediately recommended Mr. Lu to the company for the design part Apply to change the hole position from round to oval. And two days later, he also took the initiative to trial-produce a door weather strip with a round hole pitch and diameter close to Mr. Lu's trial installation. As a result, Mr. Lu was very satisfied with the ease of assembly and reported this suggestion to the company for optimization.

Two months later, Mr. Lu called and said that because of Aoqun’s professional guidance to him, the door weather strips optimization plan he reported was affirmed by the company.
