Mr. Hu is mainly engaged in aquaculture equipment business. Recently he needs to find a filter stem brush processing factory. The filter stem brush looks simply, but it is not easy to make. The filter stem brushes before were neither able to hang the film, or the workmanship was rough and often lose filament.

Mr. Hu and Mr. Liu are very good friends. After listening to Mr. Hu's request, Mr. Liu recommended Mr. Hu's best-selling green cross filament filter stem brush and told Mr. Hu: It is a brush processing factory specializing in filter stem brushes, so it will launch different filter stem brush products at any time according to market demand. For example, the cross filament filter stem brush are produced with a new cross brush filament. The unique angular structure of the cross filament can be very good. In order to prevent the filament from loosening, the filter stem brushes are strictly tested at the factory to withstand the pull-out force to ensure that the brushes will not lose filament after the biofilm is loaded. " At the suggestion of Mr. Liu, Mr. Hu provided a sample of cross-shape filament filter stem brush for Mr. Hu.

Half a month later, Mr. Hu contacted Mr. Liu again to place an order. Mr. Hu told Mr. Liu: "After customers saw the samples of Aoqun, they were very satisfied with the product, and immediately determined that Aoqun is the filter stem brush that they need long-term cooperation Processing plants.
