英语翻译这个问题本来是可以避免的,正如XXX说的,你们工厂应该在生产前对不同的XXX进行区分和隔离,而不是完全依赖QC检

The problem could have been avoided. As XXX said, before the production started, your factory should have XXX distinguished and separated in stead of depending entirely on the check conducted QC. If it is possible, I am planning to attend your internal meetings regarding product quality so as to get some ideas about what your strategies are in dealing with recent problems.
